Commit 079b35a2 ("arm: a37xx: pci: Increase PCIe MEM size from 16 MiB
to 127 MiB") increased size of PCIe MEM to 127 MiB, which is the maximal
possible size for allocated 128 MiB PCIe window. PCIe IO size in that
commit was unchanged.

Armada 3720 PCIe controller supports 32-bit IO space mapping so it is
possible to assign more than 64 KiB if address space for IO.

Currently controller has assigned 127 MiB + 64 KiB memory and therefore
there is 960 KiB of unused memory. So assign it to IO space by increasing
IO window from 64 KiB to 1 MiB.

The PLL functions take ulong arguments for rate, but still check if that
rate is negative (which is never true). The correct way to handle this is
to use IS_ERR_VALUE (like is already done in k210_clk_set_rate). While
we're at it, we can move the error checking up into the caller of the pll
set/get rate functions.  This also protects our other calculations from
using bogus values for rate.
