[PATCH v1 1/1] mmc: core: control EXT_CSD_CACHE_CTRL from device tree

[Liming Sun]

Currently the EXT_CSD_CACHE_CTRL register is controlled by API
mmc_card_broken_hpi(), which only works for the quirks settings.
This commit enhances it to use card->ext_csd.hpi instead. This
flag works for both the quirks and the broken-hpi configuration
in the device tree.
