ARM: uniphier: print Support Card info very late

Since commit 26b09c022ab6 ("ARM: uniphier: move SBC and Support Card
init code to U-Boot proper"), the System Bus is initialized by
board_init(). The show_board_info() is called from board_init_f()
by default, so the revision register of the Micro Support Card may
not be accessed at this point. Show its revision after the System
Bus is initialized.

flash: complete CONFIG_SYS_NO_FLASH move with renaming

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.

During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will
make the code more readable. Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.

This commit was created as follows:

[1] Edit "default n" to "default y" in the config entry in
common/Kconfig.

[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"

[3] Rename the instances in defconfigs by the following:
find . -path './configs/*_defconfig' | xargs sed -i \
-e '/CONFIG_SYS_NO_FLASH=y/d' \
-e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

[4] Change the conditionals by the following:
find . -name '*.[ch]' | xargs sed -i \
-e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
-e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
-e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
-e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'

[5] Modify the following manually
- Rename the rest of instances
- Remove the description from README
- Create the new Kconfig entry in drivers/mtd/Kconfig
- Remove the old Kconfig entry from common/Kconfig
- Remove the garbage comments from include/configs/*.h

ARM: uniphier: display revision of Micro Support Card 3.6.x kindly

The revision of the original support card (rev 3.5, rev 3.6) fits in
the 8 bit width revision register. When it was extended in a weird
way, it was versioned in the format of "3.6.x" (where it should have
been "3.7", of course). What is worse, only the sub-level version
"6.x" was recorded in the 8 bit width register, completely ignoring
the compatibility of the revision register format.

This patch saves madly-versioned support cards by assuming the major
version "3" when the MSB 4 bit of the register is read as "6". With
this, the support card revision that were displayed as "6.10" is now
corrected to "3.6.10".

ARM: uniphier: add work-around to support Micro Support Card v3.6.10

Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.

The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.

This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to. A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first. What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).

For clarification, things are like this:

writel(0x00010000, MICRO_SUPPORT_CARD_RESET);

is done with two bus transactions as follows

[1] write 0x0000 to address MICRO_SUPPORT_CARD
[2] write 0x0001 to address MICRO_SUPPORT_CARD + 2

For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2. This
is what we expect.

For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.

For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse. This solution only
works for the start-up code.

ARM: uniphier: fix warnings reported by aarch64 compiler

The UniPhier SoC family has not supported ARMv8 yet, but these would
cause warnings if they were compiled with a 64bit compiler. Before
adding the ARMv8 support really, fix them now.

Because UniPhier SoCs do not support Large Physical Address Extension,
casting "phys_addr_t" into "unsigned long" would carry the address
as is.
