clk: at91: better support for the PCKs

From: Boris BREZILLON <[email protected]>

This serie implements a better support for the Programmable Clocks. The first two patch are related to changing the rate of the PCKs. The 3rd patch is a fix to handle properly the PCKRDY interrupt. The last patch is a small optimzation/simplification of the determine_rate algorithm for the PCK.

Changes since v2:
- remove unnecessary CLK_SET_RATE_GATE flag from system clk setting

Boris BREZILLON (2):
clk: at91: replace prog clk round_rate with determine_rate
clk: at91: propagate rate change on system clks

Jean-Jacques Hiblot (2):
clk: at91: fix programmable clk irq handling
clk: at91: optimization of the set_rate callback
