drivers/intel/touch: Add Intel Touch Controller driver

THC is a hardware component that interfaces between a touch sensor and
the system's SPI or I2C bus. This driver publishes data into the
Secondary System Descriptor Table (SSDT).

This driver generates the following ACPI objects:
- Device Specific Method (_DSM)
- Current Resource Settings (_CRS)
- Power resource with Status (_STA), _ON, and _OFF methods
- Device Specific Data (_DSD) for THC-I2C
- Device Reset (_RST) for THC-SPI

Template device configuration for the following supported devices:
- Wacom: THC-SPI touchscreen only
- Elan: both THC-SPI and THC-I2C touchscreen
- Hynitron: THC-I2C touchpad only

BUG=none
