If we have a partial read that is supposed to be treated as failure but
in this code we forgot to set the error code.  Return -EINVAL.

- power management improvements to intel-thc-hid driver (Even Xu)

The Nova Lake platform enhances THC with half divider capability for
clock division, allowing more granular frequency control for the THC
SPI port.

Supported frequencies include 50MHz (125MHz/2.5), 35MHz (125MHz/3.5),
and 10MHz (125MHz/8/1.5).

Enhance power management with two key improvements:
1. Hibernate support: Send POWER_OFF command when entering hibernate
   mode.
2. Conditional sleep commands: Only send POWER_SLEEP/POWER_ON commands
   during system suspend/resume when the touch device is not configured
   as a wake source, preserving Wake-on-Touch (WoT) functionality. This
   ensures proper power states while maintaining expected wake behavior.

Currently HID_PHYS is empty, which means userspace tools (e.g. fwupd)
that depend on it for distinguishing the devices, are unable to do so.
Other drivers like i2c-hid, usbhid, surface-hid, all populate it.

With this change it's set to, for example: HID_PHYS=0000:00:10.0

Each function has just a single HID device, as far as I can tell, so
there is no need to add a suffix.

Tested with fwupd 2.1.1, can avoid https://github.com/fwupd/fwupd/pull/9995

- support for HID output reports in the Quicki2c (Even Xu)

Clear the target bit fields in register before setting new values. This
ensures proper field updates by removing any existing bits that might
interfere with the new configuration.

Send POWER_SLEEP command to touch device when system enters into sleep
mode or hibernate mode to save more power; and send POWER_ON command to
take device back when system exits sleep mode.
