console: Fix pre-console flushing via cfb_console being very slow

On my A10 OlinuxIno Lime I noticed a huge (5+ seconds) delay coming from
console_init_r. This turns out to be caused by the preconsole buffer flushing
to the cfb_console. The Lime only has a 16 bit memory bus and that is already
heavy used to scan out the 1920x1080 framebuffer.

The problem is that print_pre_console_buffer() was printing the buffer once
character at a time and the cfb_console code then ends up doing a cache-flush
for touched display lines for each character.

This commit fixes this by first building a 0 terminated buffer and then
printing it in one puts() call, avoiding unnecessary cache flushes.

This changes the time for the flush from 5+ seconds to not noticable.

The downside of this approach is that the pre-console buffer needs to fit
on the stack, this is not that much to ask since we are talking about plain
text here. This commit also adjusts the sunxi CONFIG_PRE_CON_BUF_SZ to
actually fit on the stack. Sunxi currently is the only user of the pre-console
code so no other boards need to be adjusted.

env_nand: use nand_spl_load_image for readenv if SPL

The readenv() implementation of env_nand uses the mtd layer which is
unnecessary overhead in SPL when we already have a nand_spl_load_image()
function that doesn't need it. Using this instead eliminates the need
to provide a mtd_read for SPL env as well as reduces code (4KB savings in IMX6
SPL).

This commit cleanups the regulator command.
The first change, is adjusting "regulator dev" command to use
"regulator-name" constraint, for setting the operating device.
Thanks to this, the regulator_get() function is removed.

This also updates do_list() function, with loop over uclass_find_*
function calls, to prevent probe of all listed regulators.

This also cleanups the printing in command.

"Roll crc32 into hash infrastructure"

The crc32 command with no -v expects an optional 3rd argument to be an
address to store the result in. With the -v switch, the last argument
is a crc, not an address. In the case where -v is set, we should set the
HASH_FLAG_ENV flag since that will first look for the value to be a
digest value, which matches the expected API for the crc32 command.

image: android: handle default kernel address

The two tools that create android boot images, mkbootimg and the fastboot
client, set the kernel address by default to 0x10008000.

U-boot always honors this field, and will try to relocate the kernel to
whatever value is set in the header, which won't be mapped to the actual RAM on
most platforms, resulting in the kernel obviously not booting.

All the targets in U-Boot right now will download the android boot image to
CONFIG_SYS_LOAD_ADDR, which means that it will already have been downloaded to
some location that is suitable for execution.

In order to have the kernel booting even with the default boot image kernel
address, if that address is used, just execute the kernel where it is.
