soc/intel/common/gpio: Add function to read GPIO TX value
This function reads out the current value set to output for a GPIO pin. Ex: GPP_E0 is set to output int e0_val; e0_val = gpio_tx_get(GPP_E0); Signed-off-by: Cliff Huang <cliff.huang@intel.com> Change-Id: Ib02b9ab50d378eb163d91aed1576428b49cec2cf Reviewed-on: https://review.coreboot.org/c/coreboot/+/72127 Reviewed-by: Anil Kumar K <anil.kumar.k@intel.corp-partner.google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Bora Guvendik <bora.guvendik@intel.com>
