While initializing an UHS-I SD card, the mmc core first tries to switch to
1.8V I/O voltage, before it continues to change the settings for the bus
speed mode.
However, the current behaviour in the mmc core is inconsistent and doesn't
conform to the SD spec. More precisely, an SD card that supports UHS-I must
set both the SD_OCR_CCS bit and the SD_OCR_S18R bit in the OCR register
response. When switching to 1.8V I/O the mmc core correctly checks both of
the bits, but only the SD_OCR_S18R bit when changing the settings for bus
speed mode.
Rather than actually fixing the code to confirm to the SD spec, let's
deliberately deviate from it by requiring only the SD_OCR_S18R bit for both
parts. This enables us to support UHS-I for SDSC cards (outside spec),
which is actually being supported by some existing SDSC cards. Moreover,
this fixes the inconsistent behaviour.

The let the SD card use the cache, the host needs to enable it and manage
flushing of the cache, so let's add support for this.
Note that for an SD card supporting the cache it's mandatory for it, to
also support the poweroff notification feature. According to the SD spec,
if the cache has been enabled and a poweroff notification is sent to the
card, that implicitly also means that the card should flush its internal
cache. Therefore, dealing with cache flushing for REQ_OP_FLUSH block
requests is sufficient.

After the eMMC sleep command (CMD5) has been sent, the card start signals
busy on the DAT0 line, which can be monitored to understand when it's
allowed to proceed to power off the VCC regulator.
When MMC_CAP_WAIT_WHILE_BUSY isn't supported by the host the DAT0 line
isn't being monitored for busy completion, but instead we are waiting a
fixed period of time. The time corresponds to the sleep timeout that is
specified in the EXT_CSD register of the eMMC card. This is many cases
suboptimal, as the timeout corresponds to the worst case scenario.
To improve the situation add support for HW busy polling through the
->card_busy() host ops, when the host supports this.

The commit 7c7905df68 ("dt-bindings: mmc: sdhci-am654: fix compatible
for j7200") switched the compatible property from a regular enum to an
more appropriate combinatorial oneOf convention, and in the process has
introduced a duplicate ti,j721e-sdhci-4bit.
This generated the following warning on J721E boards that use the
ti,j721e-sdhci-4bit for two nodes:
"mmc@4fb0000: compatible: More than one condition true in oneOf schema"
"mmc@4f98000: compatible: More than one condition true in oneOf schema"
Remove the duplicate to fix this.

disable_irq() after request_irq() still has a time gap in which interrupts
can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ
auto-enable because of requesting.
