ACPI: x86: Call acpi_boot_table_init() after acpi_table_upgrade()
Commit 1a1c130ab757 ("ACPI: tables: x86: Reserve memory occupied by
ACPI tables") attempted to address an issue with reserving the memory
occupied by ACPI tables, but it broke the initrd-based table override
mechanism relied on by multiple users.
To restore the initrd-based ACPI table override functionality, move
the acpi_boot_table_init() invocation in setup_arch() on x86 after
the acpi_table_upgrade() one.
