Anup Patel fce8d4599b ACPI: RISC-V: Fix FFH_CPPC_CSR error handling 
commit 5b3706597b upstream.

The cppc_ffh_csr_read() and cppc_ffh_csr_write() returns Linux error
code in "data->ret.error" so cpc_read_ffh() and cpc_write_ffh() must
not use sbi_err_map_linux_errno() for FFH_CPPC_CSR.

Fixes: 30f3ffbee8 ("ACPI: RISC-V: Add CPPC driver")
