mmc: core: Support packed command for eMMC4.5 device
drivers/mmc/card/block.c | 355 --
This patch adds packed command feature of eMMC4.5.
The maximum number for packing read(or write) is offered
and exception event relevant to packed command which is
used for error handling is enabled. If host wants to use
this feature, MMC_CAP2_PACKED_CMD should be set.

This patchset modifies the existing clkdev to make SPI driver
independent of the clock names send from platform data. This
patches enables the SPI driver to request SPI bus clocks
using generic connection ID.

SPI bus clocks can be avoided passing through platform
data as spi driver is getting the bus clock using the
generic clock connection id registered via clkdev.

In mmc, there are capabilities and use the host_caps.
That capability is expressed with bit[0:31].
But now..already filled the bit[0:31]...
so we need to denote with the other capability field.
