arch/x86/acpigen: Add helpers for Store() and If (Lequal (...))
This change adds the following acpigen helpers:
a. acpigen_write_store_op_to_namestr: This generates ACPI code for
storing an ACPI OP to name string
b. acpigen_write_if_lequal_namestr_int: This generates ACPI code for
checking if operand1 and operand2 are equal where operand1 is
namestring and operand2 is an integer.
