mtd: Kconfig: add a Kconfig option to enable the support for MTD block write operations

This allows using CONFIG_IS_ENABLED(SPLMTD_WRITE) to compile out code
needed only if write support is required.
The option is added for u-boot and for SPL.

UPSTREAM: mtd: Drop duplicate MTD_PARTITIONS Kconfig option

Commit 9c5b00973bce ("Convert CONFIG_MTD_PARTITIONS et al to Kconfig")
introduced a publicly visible Kconfig entry for the
CONFIG_MTD_PARTITIONS option, while the rework on MTD partitioning
was in progress, and we somehow did not notice that the same Kconfig
entry was added by commit 4048a5c519a8 ("mtd: declare MTD_PARTITIONS
symbol in Kconfig"), but this time as an invisible entry (this can
only be selected by other options).

Keep the non-visible version of this symbol, since MTD_PARTITIONS is
not something the user should be able to enable/disable directly.

UPSTREAM: mtd: declare MTD_PARTITIONS symbol in Kconfig

UBI selects MTD_PARTITIONS which is the symbol to compile
drivers/mtd/mtdpart.c. Unfortunately, the symbol was not defined in
Kconfig and this worked only with board files defining it. Fix this by
adding a boolean in Kconfig so boards defined by defconfig files only
will work as expected.

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

drivers: mtd: add Microchip PIC32 internal non-CFI flash driver.

PIC32 internal flash devices are parallel NOR flash divided into
number of banks to allow erase-programming in one while fetch and
execution continues on other. As the flash banks are memory mapped
stored code can be executed directly from flash (XIP), also there
is additional hardware logic to prefetch and cache contents to
improve execution performance. These flash can also be used to
store user data (like environment).
Flash erase and programming are handled by on-chip NVM controller.

Driver implemented driver model but MTD is not really support.
