PARF_SLV_ADDR_SPACE_SIZE_2_3_3 macro is used for qcom_pcie_post_init_2_3_3.
PCIe slave address space size register offset is 0x358, but was wrongly
changed to 0x16c as a part of commit 39171b33f652 ("PCI: qcom: Remove
PCIE20_ prefix from register definitions"). Fixing it, by using the right
macro and remove the unused PARF_SLV_ADDR_SPACE_SIZE_2_3_3.
Without this access to the registers of slave addr space like iATU etc
are broken leading to PCIe enumeration failure on IPQ8074.
Fixes: 39171b33f652 ("PCI: qcom: Remove PCIE20_ prefix from register definitions")
