soc/amd/sabrina/include/amd_pci_int_defs: add additional UARTs 

Compared to Cezanne there are 3 more UARTs controllers. The PCI
interrupt index table in the new SoC's PPR #57243 Rev 1.50 doesn't
contain a PIRQ mapping for UART4. The reference code has a mapping for
this and it uses PIRQ mapping index 0x77 for UART4 and not for I2C5.
Since the I2C5 controller isn't owned by the x86 side and I didn't see
any mapping of the I2C5 controller into the x86 MMIO space, this seems
very plausible. Also add the corresponding fields to the ACPI code.
