The CLK_IGNORE_UNUSED flag was added on all the system clocks because of the
ddrck. Now that it is handled by the ram controller driver, we can drop it.

The PCKRDY bit is not set until the system clock is enabled.
This patch moves the management of the ready status in the system clock
driver.

System clks are just gates, and thus do not provide any rate operations.
Authorize clk rate change to be propagated to system clk parents.

This patch adds new at91 system clock implementation using common clk
framework.
Some peripherals need to enable a "system" clock in order to work properly.
Each system clock is given an id based on the bit position in SCER/SCDR
registers.
