We used to set up the GPIO used for the SMC ethernet IRQ by
requesting the GPIO line explicitly. As we recently established
that specifying the GPIO controller as interrupt parent and
requesting one of its interrupts by reference should be enough,
we do away with this. Incidentally, the Nomadik GPIO chip driver
handles this just fine: the IRQ is set up and fired as expected.

Common clock framework allows to register clock providers to get called
on of_clk_init() by using CLK_OF_DECLARE. This converts nomadik clock
provider to make use of it and get rid of the mach specific clk init
call. As clocks require system reset controller base address to be
initialized each clock driver checks src_base and calls new
nomadik_src_init if required.

Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
to 32. This is the painful way to learn that if you're using
SPARSE_IRQ and avoid to define .nr_irqs in your machine,
the first 16 IRQs will be pre-allocated, and the IRQdomain
code (as the VIC core code before it) will then assume
that all IRQ descriptors are pre-allocated, and 16 of them
are - by somebody else. So mapping the IRQs will fail in
irq_create_mapping(). Moving the offset upward rids us of
this problem.
