The MMC_CAP2_HC_ERASE_SZ is used only by a few mmc host drivers. Its intent
is to enable eMMC's high-capacity erase size, as to improve the behaviour
of the erase operations.
We should strive to avoid software configuration options that aren't
necessary, but instead deploy common behaviours. For these reasons, let's
remove the capability bit for MMC_CAP2_HC_ERASE_SZ and make it the default
behaviour.
Note that this change doesn't affect eMMCs supporting trim/discard, because
these commands operates on sectors and takes precedence over erase
commands.

Devices might save and restore tuning values so that re-tuning might not be
needed after a pm transition. Let drivers decide by pushing the
mmc_retune_needed() logic down to them.

Clear incorrect SDHCI_CAN_64BIT capability on Broadcom MIPS based SoCs.
The MIPS based SoCs are using ADMA only, but the several SoCs have the
incorrect capability bit about ADMA 64-bit. The "brcm,bcm7425-sdhci" is
compatible string for MIPS based SoC.

The field "owner" is set by core. Thus delete an extra initialisation.

Add SDHCI driver for Broadcom BRCMSTB SoCs.
This driver works with all ARM based SoCs and the 7425, 7429
and 7435 MIPS based SoCs.
The driver disables all UHS speed modes by default and relies
on the Device Tree node properties to enable these modes for
SoC/Board combinations that support them.
