[PATCH v7 01/10] iommu/generic_pt: Fix the RISC-V supported feature mask

[fangyu.yu at linux.alibaba.com]

From: Andrew Jones <andrew.jones at oss.qualcomm.com>

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")
