Add SDMA, ADMA2 and 26b data length support.
If V4 64 bit address mode is supported in capabilities register,
program controller to enable V4 host mode and use appropriate
SDMA registers supporting 64 bit addresses.
If V4 64 bit address mode is supported in capabilities register,
program controller to enable V4 host mode and use appropriate
ADMA descriptors supporting 64 bit addresses.
If host controller version is above V4.0, enable ADMA2 with 26b data
length support for better performance. HC 2 register is configured to
use 26 bit data lengths and ADMA2 descriptors are configured appropriately.

Some SdMmc host controllers are run by clocks with different
frequency than it is reflected in Capabilities Register 1.
It is allowed by SDHCI specification ver. 4.2 - if BaseClkFreq
field value of the Capability Register 1 is zero, the clock
frequency must be obtained via another method.
Because the bitfield is only 8 bits wide, a maximum value
that could be obtained from hardware is 255MHz.
In case the actual frequency exceeds 255MHz, the 8-bit BaseClkFreq
member of SD_MMC_HC_SLOT_CAP structure occurs to be not sufficient
to be used for setting the clock speed in SdMmcHcClockSupply
function.
This patch adds new UINT32 array ('BaseClkFreq[]') to
SD_MMC_HC_PRIVATE_DATA structure for specifying
the input clock speed for each slot of the host controller.
All routines that are used for clock configuration are
updated accordingly.
This patch also adds new IN OUT BaseClockFreq field
in the Capability callback of the SdMmcOverride,
protocol which allows to update BaseClkFreq value.
The patch reuses original commit from edk2-platforms:
20f6f144d3a8 ("Marvell/Drivers: XenonDxe: Allow overriding base clock
frequency")

Some SD Host Controllers use different values in Host Control 2 Register
to select UHS Mode. This patch adds a new UhsSignaling type routine to
the NotifyPhase of the SdMmcOverride protocol.
UHS signaling configuration is moved to a common, default routine
(SdMmcHcUhsSignaling). After it is executed, the protocol producer
can override the values if needed.

Clock control is similar in SDHCI versions greater then version 2. Add
support for more recent versions of the controller specification.
SD card support for 1.8V is also present in controller versions 3 and
greater.
