[coreboot-gerrit] Change in coreboot[master]: acpigen: Add some new helper functions

[Duncan Laurie (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/41985

to look at the new patch set (#3).

Change subject: acpigen: Add some new helper functions
......................................................................

acpigen: Add some new helper functions

These build on existing functions but use different object types
in order to provide functions for upcoming changes:

acpigen_write_return_op(): Return an operator.
acpigen_write_if_lequal_op_op(): Check if 2 operands are equal.
acpigen_get_package_op_element(): Read an element from a package
                                  into an operator.

This one just provides the missing helper, the other 3 already exist:
acpigen_get_tx_gpio: Read TX gpio state.
