acpigen: Add more useful helper functions
acpigen_write_debug_namestr() - Debug = NAME
acpigen_write_return_namestr() - Return (NAME)
acpigen_set_package_op_element_int() - Set package pointer element
DeRefOf (PKG[ELEM]) = INT
acpigen_get_package_element() - Get package (not pointer) element
dest_op = PKG[ELEM]
acpigen_set_package_element_int() - Set package element to integer
PKG[ELEM] = INT
acpigen_set_package_element_namestr() - Set package element to namestr
PKG[ELEM] = NAME
acpigen_write_delay_until_namestr_int() - Delay while waiting for
register to equal expected value.
