This patch adds lpi2c bus driver to support new i.MX products
which use lpi2c instead of the old imx i2c.

The lpi2c can continue operating in stop mode when an appropriate
clock is available. It is also designed for low CPU overhead with
DMA offloading of FIFO register accesses.

010b - Clock option 2
011b - Clock option 3
100b - Clock option 4

val = ffs(val) - 1;

if (val && (mux->flags & CLK_MUX_INDEX_ONE))
val--;

The val is 0, so the parent will be returned as first
clock parent in PCC register field which is 001b,
that will cause setting clk parent fail when the
reset value is 0 and we try to set clk parent to
option 1, as clk driver thinks current clk parent
is same as the new parent.

clk gate is controlled by bit 30, so it would NOT impact
