ARM: tegra: split tegra_pmc_init() in two
Tegra's board file currently initializes clocks much earlier than those
for most other ARM SoCs. The reason is:
* The PMC HW block is involved in the path of some interrupts (i.e. it
inverts, or not, the IRQ input pin dedicated to the PMIC).
* So, that part of the PMC must be initialized early so that the IRQ
polarity is correct.
* The PMC initialization is currently monolithic, and the PMC has some
clock inputs, so the init routine ends up calling of_clk_get_by_name(),
and hence clocks must be set up early too.
In order to defer clock initialization to the more typical location,
split out the portions of tegra_pmc_init() that are truly IRQ-related
into a separate tegra_pmc_init_irq(), which can be called from the
machine descriptor's .init_irq() function, and defer the rest until
the machine descriptor's .init_machine() function. This allows the
clock initiliazation to happen from the machine descriptor's
.init_time() function, as is typical.
