This patch series is comprised of 5 patches. The first two patches are to add documentation
for firmware loading. The third and fourth patches introduce support for the 'Load Main
Firmware from Host' feature in the ISHTP driver, applicable to Lunar Lake and subsequent
platforms. The last patch enhances the firmware reset handler in the ISH driver. This
addresses an issue where the driver receives two MNG_RESET_NOTIFY messages upon implementing
the 'Load Main Firmware from Host' feature.

This patch series is based on the following 3 commits, which have already been included in the linux-next/master branch.
- HID: intel-ish-hid: ipc: Fix dev_err usage with uninitialized dev->devc
- HID: intel-ish-hid: Use PCI_VDEVICE() and rename device ID macros
- HID: intel-ish-hid: ipc: Add Lunar Lake-M PCI device ID
