[PATCH v2 2/3] configs: ibex-ast2700: Explicitly disable Zaamo and Zalrsc extension

[Yao Zi]

This board supports neither Zaamo nor Zalrsc extension, thus we want to
build it without "a" specified in the ISA string passed to compiler in
case of misused A-extension instructions. With RISCV_ISA_ZAAMO and
RISCV_ISA_ZALRSC Kconfig options introduced, we must explicitly disable
both of them to achieve this.
