[RFC PATCH v2 4/7] RISC-V: KVM: Remove 's' & 'u' as valid ISA extension

[Atish Patra]

There are no ISA extension defined as 's' & 'u' in RISC-V specifications.
The misa register defines 's' & 'u' bit as Supervisor/User privilege mode
enabled. But it should not appear in the ISA extension in the device tree.

Remove those from the allowed ISA extension for kvm.
