The driver uses its own definitions for HID requests.
This leads to duplication and obfuscation. Use HID's
definitions.

Without a reported resolution, userspace was assuming 1 unit/mm which
is wildly wrong: a regular smartphone is clearly not 2.4 meters tall.
Most applications do not care much for this kind of raw mm value,
but Phosh's on-screen keyboard would accidentally trigger swipe-to-close
gestures due to misinterpreting small movements as huge ones.
Do what the older goodix.c driver does and set the resolution to 10
units/mm to make sure the numbers calculated by userspace are reasonable.

Instead of requesting interrupt normally and immediately disabling it
with call to disable_irq() use IRQF_NOAUTOEN to keep it disabled until
it is needed. This avoids a tiny window when interrupt is enabled but
not needed.

Guard notation simplifies code.
Also use list_first_entry() instead of list_entry() to emphasize intent.

Guard notation simplifies code.
Also stop trying to check if input device is opened/in use in the
interrupt handler - the interrupt is disabled when device is closed or
suspended.

Using guard notation makes the code more compact and error handling
more robust by ensuring that locks are released in all code paths
when control leaves critical section.

Do not define or use iqs5xx_ihex_rec structure: the original code was
using just a couple of fields in it and instead used it to calculate
offset to record data. The data field was actually reserving space for
checksum.
Instead iterate through fields and advance pointer explicitly.

Guard notation simplifies code.
Note that callers of exc3000_vendor_data_request() always expect
response, so it was adjusted to always wait for it.
