Device drivers should not access MMIO registers through hardcoded
platform specific address constants. Instead, we can pass the
MMIO token to the spear clock driver in the initialization routine
to contain that knowledge in the platform code itself.

Ideally, the clock driver would use of_iomap() or similar to
get the address, and that can be used later, but for now, this
is the minimal change.

Dummy clocks were added for ARM platforms, so that clk_get() for interface clk
doesn't fail for amba devices from amba_probe(). Because there is no amba device
for SPEAr that doesn't have a valid clock with dev_id for SPEAr, we don't need
these dummy clocks. Hence, remove them.

Flag CLK_SET_RATE_PARENT is required for a clock, where we want to
propagate clk_set_rate to its parent. This patch adds this to multiple clocks.

The max limit of con_id is 16 and dev_id is 20. As of now for spear3xx, many clk
ids are exceeding this predefined limit.

This patch is intended to rename clk ids like:
    mux_clk -> _mclk
    gate_clk -> _gclk
    synth_clk -> syn_clk
    ras_gen1_synth_gate_clk -> ras_syn1_gclk
    ras_pll3_48m -> ras_pll3_
    pll3_48m -> pll3_

SPEAr SoCs used its own clock framework since now. From now on they will move to
use common clock framework.

This patch updates existing SPEAr machine support to adapt for common clock
framework.
