Subject: [PATCH 01/15] KVM: riscv: selftests: Generate ISA extension reg_list using macros
Various ISA extension reg_list have common pattern so let us generate
these using macros.
We define two macros for the above purpose:
1) KVM_ISA_EXT_SIMPLE_CONFIG - Macro to generate reg_list for
ISA extension without any additional ONE_REG registers
2) KVM_ISA_EXT_SUBLIST_CONFIG - Macro to generate reg_list for
ISA extension with additional ONE_REG registers
