a5a056c8d2 HID: intel-thc: fix CONFIG_HID dependency 
In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the
drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use
'select HID'. With the newly added INTEL_THC_HID, this causes a build
warning for a circular dependency:

WARNING: unmet direct dependencies detected for HID
  Depends on [m]: HID_SUPPORT [=y] && INPUT [=m]
  Selected by [y]:
  - INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y]

WARNING: unmet direct dependencies detected for INPUT_FF_MEMLESS
  Depends on [m]: INPUT [=m]
  Selected by [y]:
  - HID_MICROSOFT [=y] && HID_SUPPORT [=y] && HID [=y]
  - GREENASIA_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_GREENASIA [=y]
  - HID_WIIMOTE [=y] && HID_SUPPORT [=y] && HID [=y] && LEDS_CLASS [=y]
  - ZEROPLUS_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ZEROPLUS [=y]
  Selected by [m]:
  - HID_ACRUX_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ACRUX [=m]
  - HID_EMS_FF [=m] && HID_SUPPORT [=y] && HID [=y]
  - HID_GOOGLE_STADIA_FF [=m] && HID_SUPPORT [=y] && HID [=y]
  - PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m]

It's better to be consistent and always use 'depends on HID' for HID
drivers. The notable exception here is USB_KBD/USB_MOUSE, which are
alternative implementations that do not depend on the HID subsystem.

Do this by extending the "if HID" section below, which means that a few
of the duplicate "depends on HID" and "depends on INPUT" statements
can be removed in the process.

a688404b2e HID: intel-thc-hid: intel-thc: Add THC DMA interfaces 
As THC PIO only has 64 bytes FIFO length, THC DMAs are introduced to
send/receive large data packets.

THC has three types of DMA channels: Read DMA channel (RxDMA), Write DMA
channel (TxDMA) and Software DMA (SWDMA).

In addition to basic DMA functions, THC RxDMA also includes an auto
hardware sequence which can handle external touch device's interrupt
automatically without software involved. THC RxDMA channel usually is
used for handling touch input reports.

THC TxDMA is very similar with general IO TxDMA, and usually is used
for sending command/request to exteranl touch device.

THC SWDMA can perform read, write followed by read operation
according to different configurations. Unlike RxDMA triggered by bus
activity, SWDMA can be triggered by SW driver at any time, for example:
- Retrieving an input report without interrupt
- Sending command followed by reading response

THC DMA operation flow includes 4 steps:
1. Allocate DMA buffers
2. Configure opcode, fill PRD table with DMA buffers, enable DMA channel
3. Wait for completion, read out DMA buffers and update buffer pointers
4. Stop DMA and release DMA buffers

THC Hardware layer driver provides APIs for all above DMA Steps.

2. start: set start bit to issue a bus send/receive
3. wait: wait for bus sending/receiving completion
4. complete: check send/receive data in FIFO and return
