[PATCH 6/6] riscv: Add a wrapper to call sbi_ecall for base extension

[cem@kernel.org <cem@kernel.org>]

From: Carlos Maiolino <cem@kernel.org>

All SBI extension functions accepts at most one argument, so create a
wrapper around sbi_ecall() to avoid needing to pass in arguments 1 to 5
all the time, also, the wrapper can specify SBI_EXT_BASE directly.
