drivers: Remove TODO from io_fip.c

The comment suggests checking version numbers and
a checksum but there doesn't seem to be any usable
data for either of these.

For example, fip_toc_header_t doesn't contain any
version information and neither does fip_toc_entry_t.

As the function name "is_valid_header" suggests, this
function is not concerned with checksumming any of
the table of contents entries.

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

- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller

Due to the shared Mbed TLS heap optimisation introduced in 6d01a463,

This commit improves the SDHost driver for RPi3 as following:
* Unblock MMC_CMD(17). Using MMC_CMD(17) is more efficient on
block reading.
* In some low probability that SEND_OP_COND might results CRC7
error. We can consider that the command runs correctly. We don't
need to retry this command so removing the code for retry.
* Using MMC_BUS_WIDTH_1 as MMC default value to improve the stability.
* Increase the clock to 50Mhz in data mode to speed up the io.
* Change the pull resistors configuration to gain more stability.
