Tien Hock, Loh 2baa727011 driver: synosys: Fix SD MMC not initializing correctly
dw_params.mmc_dev_type should be assigned before mmc_init, otherwise SDMMC
initialization will fail as the initialization treats the device as EMMC
instead of SD.

Tien Hock, Loh 3d0f30bb54 drivers: synopsys: Fix synopsys MMC driver
There are some issues with synopsys MMC driver:
- CMD8 should not expect data (for SD)
- ACMD51 should expect data (Send SCR for SD)
- dw_prepare should not dictate size to be MMC_BLOCK_SIZE, block size is
now handled in the dw_prepare function
- after the CMD completes, when doing dw_read, we need to invalidate cache
and wait for the data transfer to complete
- Need to set FIFO threshold, otherwise DMA might never get the interrupt
to read or write

Antonio Nino Diaz 09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Yann Gautier 97d5db8c5c mmc: Update framework to use standard response type
Respect official response type and update response to follow
official specification.
All the MMC_RESPONSE_R(_x) are replaced with each corresponding define.

Partly revert 2a82a9c95f for dw_mmc.c:
Responses R1, R1B and R5 have CRC.
