pci: pci_mvebu: Remove dependency on SOC_REGS_PHY_BASE macro

SoC specific macro SOC_REGS_PHY_BASE is used for two things:

* calculation of base PCIe port address
* filling PCIe register with address of internal registers

For calculating base PCIe port address use function
ofnode_translate_address() which translates DT "assigned-addresses" to
final PCIe port address.

And for calculating address of internal registers use untranslated and
translated DT "assigned-addresses".

Basically this change reads SOC_REGS_PHY_BASE address indirectly from DT.
