Re-enable ADMA2 support for arasan,sdhci-8.9a

Disable ADMA2 on the Arasan SDHCI 8.9A found in the Xilinx Zinq-7000 due
to sporadic transfer errors until the root cause for the errors is found.
In the meantime, SDMA works fine on this platform.

No need to constrain DMA tag to 32-bits on 32-bit platforms.

Use generic Arasan SDHCI driver for Zynq-7000.

sdhc: Retire SDHC_FLAG_USE_ADMA2 flag.

ADMA2 support in sdhc is mature now, so no need for it to be opt-in.

Use __MASK(4) in bus_dmatag_subregion. NFCI.

s/0xffffffff/UINT32_MAX/ in bus_dmatag_subregion call

Rename of_match_compat_data() to of_compatible_match(). Similarly,
rename of_search_compatible() to of_compatible_lookup().

Standardize on of_compatible_match() for driver matching, and adapt
all call sites.

Remove "struct of_compat_data" and replace its usage with
"struct device_compatible_entry"; they are ABI-compatible.

Fix several "loses const qualifier" bugs encountered during
this conversion.
