core: mm: Rename "mva" to "va" for TLB operations

The terminology "mva" is specific for older ARM architecture which has
FCSE extension. To support multiple architecture, it would be good to
rename "mva" to common terminology, such as "va". This PR renames "mva"
to "va" in TLB operations for ARM64 and RISC-V. For ARM32, "mva" is
reserved because it is really defined in ARM32's documentations.
