spl: mmc: refactor device location code to its own function

Simplify spl_mmc_load_image() code by moving the part that finds the mmc device
into its own function spl_mmc_find_device(), available in two flavors: DM and
non-DM.

This refactor fixes a bug in which an error in the device location sequence
does not necessarily aborts the rest of the code. With this refactor, we fail
the moment there is an error.

spl: mmc: add break statements in spl_mmc_load_image()

The original intention of the mmc load_image() function was to try multiple
boot modes before failing. This is evident by the lack of break statements
in the switch, and the following line in the default case:
puts("spl: mmc: no boot mode left to try\n");

This implementation is problematic because:
- The availability of alternative boot modes is very arbitrary since it
depends on the specific order of the switch cases. If your boot mode happens to
be the first case, then you'll have a bunch of other boot modes as alternatives.
If it happens to be the last case, then you have none.
- Opting in/out is tied to config options, so the only way for you to prevent an
alternative boot mode from being attempted is to give up on the feature completely.
- This implementation makes the code more complicated and difficult to
understand.

Address these issues by inserting a break statements between the cases to make the
function try only one boot mode.

board_init: Change the logic to setup malloc_base

Prior to commit 5ba534d247d418 ("arm: Switch 32-bit ARM to using generic
global_data setup") we used to have assembly code that configured the
malloc_base address.

Since this commit we use the board_init_f_mem() function in C to setup
malloc_base address.

In board_init_f_mem() there was a deliberate choice to support only
early malloc() or full malloc() in SPL, but not both.

Adapt this logic to allow both to be used, one after the other, in SPL.

This issue has been observed in a Congatec board, where we need to
retrieve the manufacturing information from the SPI NOR (the SPI API
calls malloc) prior to configuring the DRAM. In this case as malloc_base
was not configured we always see malloc to fail.

With this change we are able to use malloc in SPL prior to DRAM gets
initialized.

Also update the CONFIG_SYS_SPL_MALLOC_START entry in the README file.

sparse: Implement several chunks flashing

The fastboot client will split the sparse images into several chunks if the
image that it tries to flash is bigger than what the device can handle.

In such a case, the bootloader is supposed to retain the last offset to
which it wrote to, so that it can resume the writes at the right offset
when flashing the next chunk.

Retain the last offset we used, and use the session ID to know if we need
it or not.

fastboot: Implement flashing session counter

The fastboot flash command that writes an image to a partition works in
several steps:

1 - Retrieve the maximum size the device can download through the
"max-download-size" variable

2 - Retrieve the partition type through the "partition-type:%s" variable,
that indicates whether or not the partition needs to be erased (even
though the fastboot client has minimal support for that)

3a - If the image is smaller than what the device can handle, send the image
and flash it.

3b - If the image is larger than what the device can handle, create a
sparse image, and split it in several chunks that would fit. Send the
chunk, flash it, repeat until we have no more data to send.

However, in the 3b case, the subsequent transfers have no particular
identifiers, the protocol just assumes that you would resume the writes
where you left it.

While doing so works well, it also means that flashing two subsequent
images on the same partition (for example because the user made a mistake)
would not work withouth flashing another partition or rebooting the board,
which is not really intuitive.

Since we have always the same pattern, we can however maintain a counter
that will be reset every time the client will retrieve max-download-size,
and incremented after each buffer will be flashed, that will allow us to
tell whether we should simply resume the flashing where we were, or start
back at the beginning of the partition.
