This driver adds support for the keyboard on Apple Silicon laptops.
The controller for this keyboard sits on an SPI bus and uses an
Apple-specific HID over SPI protocol. The packets sent by this
controller for key presses and key releases are fairly simple and
are decoded directly by the code in this driver and converted into
standard Linux keycodes. The same controller handles the touchpad
found on these laptops. Packets for touchpad events are simply
ignored.

Migrate TEGRA_KEYBOARD from headers to Kconfig, only the seaboard uses it but we
drop CONFIG_KEYBOARD as the driver doesn't use the legacy drv_keyboard_init.

In some cases it is necessary to read the keyboard in early phases of
U-Boot. Update the config to allow this.

This converts the following to Kconfig:
CONFIG_TWL4030_LED
CONFIG_TWL4030_INPUT
This also removes dead references to:
CONFIG_TWL4030_KEYPAD

Creating multiple entries of "config FOO" often gives us bad
experiences. In this case, we should specify "default X86"
as platforms that want this keyboard by default.

Add a new option CONFIG_I8042_KEYB which will replace the current
CONFIG_I8042_KBD. This new name fits better with existing drivers.

This is enabled by a new CONFIG_DM_KEYBOARD option.

Since both I2C and SPI are converted to Kconfig, we can convert cros_ec
to Kconfig for these buses.
LPC will need to wait until driver mode PCI is available.
