falco: Add on-board devices and configure GPIO irq/wake
Add the onboard I2C devices for Falco trackpad/lightsensor
and generate SMBIOS Type41 tables for them.
Add ACPI device for the trackpad to expose the interrupt map
to the OS so it can be used.
Configure interrupt GPIOs as PIRQ type and wake GPIOs as
just standard input type. The wake GPIO is reconfigured as
ACPI SCI in the specific device _DSW method. This prevents
the wake GPIO from generating a flood of SCI at runtime.
LTE_WAKE_L_Q and WLAN_WAKE_L_Q are left as ACPI SCI as these
are not repurposed interrupt pins so they are not generated
at runtime.
SIM_DET and ALS_INT_L are set as input since we don't have an
interrupt handler for them.
