Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.Signed-off-by: Stephen Boyd

The AT91 clock drivers make use of IRQs to avoid polling when waiting for
some clocks to be enabled. Unfortunately, this leads to a crash when those
IRQs are threaded (which happens when using preempt-rt) because they are
registered before thread creation is possible.Use polling on those clocks instead to avoid the problem.

Use the regmap coming from syscon to access the registers instead of using
pmc_read/pmc_write. This allows to avoid passing the at91_pmc structure to
the child nodes of the PMC.The final benefit is to have each clock register itself instead of having
to iterate over the children.Signed-off-by: Boris Brezillon

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.Signed-off-by: Alexandre Belloni

System clks are just gates, and thus do not provide any rate operations.

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.Signed-off-by: Boris BREZILLON
