mb/google/bluey: Add GPIOs for Soundwire, Display, and SD Card

Browse source 
This commit introduces several new GPIO definitions and a Kconfig
option for the Bluey mainboard to support additional hardware features.

Kconfig changes:

 - MAINBOARD_HAS_SD_CONTROLLER: To indicate the presence of an SD card
   controller. It defaults to 'n'.

GPIO changes (in board.h):

 - Soundwire Amplifier GPIOs:
     - GPIO_SNDW_AMP_0_ENABLE (GPIO 204)
     - GPIO_SNDW_AMP_1_ENABLE (GPIO 205)

 - Display specific GPIOs:
     - GPIO_PANEL_POWER_ON (GPIO 70)
     - GPIO_PANEL_HPD (GPIO 119)

 - SD Card specific GPIO:
     - GPIO_SD_CD_L (GPIO 71): This GPIO is conditionally defined based
       on the new CONFIG_MAINBOARD_HAS_SD_CONTROLLER option.

Source: Bluey schematics (dated 04/15).
