Subject: [PATCH -next 0/2] RISC-V: ACPI: Add LPI support

This series adds support for Low Power Idle (LPI) on ACPI based
platforms. 

LPI is described in the ACPI spec [1]. RISC-V FFH spec required to
enable this is available at [2].

[1] - https://uefi.org/specs/ACPI/6.5/08_Processor_Configuration_and_Control.html#lpi-low-power-idle-states 
[2] - https://github.com/riscv-non-isa/riscv-acpi-ffh/releases/download/v/riscv-ffh.pdf
