Subject: [PATCH v4 6/9] acpi: Move setting CAP_SMP_T_SWCOORD to arch_acpi_set_proc_cap_bits()

Currently ACPI_PROC_CAP_SMP_T_SWCOORD is set in acpi_set_pdc_bits().
This doesn't make any sense, as it isn't _PDC specific. It should be
moved to arch code for coherency.

Move setting of ACPI_PROC_CAP_SMP_T_SWCOORD to
arch_acpi_set_proc_cap_bits().
