These imx5 init_early[late] hooks are called only from mach-imx5x.c.
Let's move them into mach-imx5x.c.

While at it, replace the static mapping in imx51_ipu_mipi_setup() with
dynamic mapping.  Also this function and imx_src_init() do not

.init_machine.

The mxc_iomux_v3_init() is dropped from imx51_init_early() in the
moving, since it's only needed by non-DT boot.

Replace the static mapping of DPLL block with dynamic mapping by
calling ioremap().  Ideally, this should be done by calling of_iomap(),
so that the physical address of DPLL can also be retrieved from device
tree.  But unfortunately, DPLL blocks are not defined in DT in the first
place.  So to maintain the compatibility of existing DTB, we use
ioremap() with physical address defines in the code.

The i.MX6 reference manual doesn't make a clear distinction
between the fixed clock divider and the enable gate for the
pcie and sata reference clocks. This lead to the lvds mux
inputs in the imx6q clk driver to be parented from the
ref clock (which is the divider) instead of the actual gate,
which in turn prevents the upstream clock to actually be
enabled when lvds clk out is active.

This fixes a hard machine hang regression in kernel 3.16 for
boards where only pcie is active but no sata, as with this
kernel version the imx6-pcie driver is no longer enabling
the upstream clock directly but only lvds clk out.

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
  eventually get rid of CACHE_PL310, surround these errata options with an
  if CACHE_L2X0 conditional rather than repeating the dependency against
  each.

This config exists entirely to hide the cpufreq menu from the

is actually built if this config is 'Y' and it just leads to more

that we can always enable CPUfreq drivers on ARM platforms.
