[PATCH] iommu/generic_pt: Fix the RISC-V supported feature mask

The RISC-V format advertises Svpbmt to its users, but omits the feature
from PT_SUPPORTED_FEATURES. Add it there so configurations which enable
Svpbmt pass generic page-table feature validation.

Fixes: f196a8668797 ("iommu/riscv: Advertise Svpbmt support to generic page table")
