mmc: core: Add support for SDIO wakeup interrupt

If wakeup-source flag is set in host dts node, parse EAI information
from SDIO CCCR interrupt externsion segment for in-band wakeup. If
async interrupt is supported by SDIO card then enable it and set
enable_async_irq flag in sdio_cccr structure to 1. The parse flow is
implemented in sdio_read_cccr().

mmc: sdio: fix setting card data bus width as 4-bit

mmc: sdio: fix setting card data bus width as 4-bit

SDIO_CCCR_IF[1:0] in SDIO card is used for card data bus width
setting as below:

00b: 1-bit bus
01b: Reserved
10b: 4-bit bus
11b: 8-bit bus (only for embedded SDIO)

And sdio_enable_wide is for setting data bus width as 4-bit.
But currently, it first reads the register, second OR' 1b with
SDIO_CCCR_IF[1], and then writes it back.

As we can see, this is based on such assumption that the
SDIO_CCCR_IF[0] is always 0. Apparently, this is not right.

mmc: sdio: support SDIO UHS cards

This patch adds support for sdio UHS cards per the version 3.0
spec.

UHS mode is only enabled for version 3.0 cards when both the
host and the controller support UHS modes.

1.8v signaling support is removed if both the card and the
host do not support UHS. This is done to maintain
compatibility and some system/card combinations break when
1.8v signaling is enabled when the host does not support UHS.

mmc: avoid getting CID on SDIO-only cards

The introduction of support for SD combo cards breaks the initialization
of all CSR SDIO chips. The GO_IDLE (CMD0) in mmc_sd_get_cid() causes CSR
chips to be reset (this is non-standard behavior).

When initializing an SDIO card check for a combo card by using the memory
present bit in the R4 response to IO_SEND_OP_COND (CMD5). This avoids the
call to mmc_sd_get_cid() on an SDIO-only card.
