Introduce CONFIG_IMAGE_SPARSE and CONFIG_CMD_MMC_SWRITE so the "mmc
swrite" command is separated from the fastboot code.

Move image-sparse from common to lib so it's clear it's library code.

Rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE
and migrate it to Kconfig.

Add the response string as a parameter to fastboot_okay/fail, instead
of modifying a global, to match the contract expected by the AOSP
U-Boot code.

Convert CONFIG_SUPPORT_EMMC_RPMB to Kconfig. Split the command handling
from the underlying support and expose this through CMD_MMC_RPMB.

Provide an alternate path for sparse-images to be
written to MMC. For example, via tftp on platforms
that don't support fastboot protocol. Or when an
image is to written at some offset, rather than the
start of a partition.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

hc_wp_grp_size is needed only if hardware partitionning is used.
On ARM removing it saves about 30 bytes of code space.

Also remove erase_grp_size and write_bl_len from struct mmc as they are
not used anymore. On ARM, removing them saves about 100 bytes of code
space in SPL.

Not all boards have an eMMC and not all users have a need for this.
Allow to compile it out. By default it is still included.

This is a useful information while debugging the initialization process or
performance issues.
Also dump this information with the other mmc info if the verbose option
is selected
