PCI: qcom: Fix IPQ8074 enumeration

PARF_SLV_ADDR_SPACE_SIZE_2_3_3 is used by qcom_pcie_post_init_2_3_3().
This PCIe slave address space size register offset is 0x358 but was
incorrectly changed to 0x16c by 39171b33f652 ("PCI: qcom: Remove PCIE20_
prefix from register definitions").

This prevented access to slave address space registers like iATU, etc.,
so the IPQ8074 PCIe controller was not enumerated.

Revert back to the correct 0x358 offset and remove the unused
PARF_SLV_ADDR_SPACE_SIZE_2_3_3.

Fixes: 39171b33f652 ("PCI: qcom: Remove PCIE20_ prefix from register definitions")
