This patch abstracts out the CNF area code from tmio_mmc which
is not present in all hardware that can use this driver. This
is required so that we can support non-toshiba based hardware.

We can not have .driver_data as const since platform_set_drvdata() doesnt take
a const.
The hclk mmc_data field can be const though.

The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK
and AMD Imageon w228x's HCLK is 80 MHz. With this patch, the MFD driver
provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.

Add driver for TMIO framebuffer cells as found e.g. in Toshiba TC6393XB
chips.
