Jianjun Wang 69f0bebe91 PCI: mediatek-gen3: Fix translation window size calculation 
[ Upstream commit 9ccc1318cf ]

When using the fls() helper, the translation table should be a power of
two; otherwise, the resulting value will not be correct.

For example, given fls(0x3e00000) - 1 = 25, the PCIe translation window
size will be set to 0x2000000 instead of the expected size 0x3e00000.

Fix the translation window by splitting the MMIO space into multiple tables
if its size is not a power of two.
