[PATCH] HID: intel-thc-hid: Remove deprecated PCI API calls

[Philipp Stanner <phasta@kernel.org>]

intel-thc-hid reintroduced the already deprecated PCI API functions

	pcim_iomap_table(),
	pcim_iomap_regions(),
	pcim_iounmap_regions(),

none of which should be used anymore.

Furthermore, calling managed (pcim_*) functions in remove() and probe()
for cleanup is not necessary, since the managed functions clean up
automatically.

Replace / remove the deprecated functions.

Fixes: 61bb2714dc3a1 ("HID: intel-thc-hid: intel-quicki2c: Add THC QuickI2C driver skeleton")

Hi,

I'm trying to remove this API since a year. Please pay attention to the
docstrings in PCI which mark certain functions as deprecated.

Thanks
P.
