This reverts commit a8e67c9d.

Current driver does not work on EVM because we need to enable ATA
pins via the GPIO expander. This is not the best way to do it, but I
don't have a better one yet.

Troy found that mmc_davinci_start_command was previously enabling

while the FIFO was being stuffed, resulting in an overstuffed fifo.

Interrupts are enabled at the point where
the DAVINCI_I2C_IVR_REG is read, so unless
an interrupt happened just at that moment,
no interrupt would be pending. Even though
documentation implies you should do this,
I see no reason. If slave support is added,
this read would cause a hard to reproduce bug.

These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.

Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.

Add support for DPLLs function in locked and bypass clock modes.
