HID: Handle driver-specific device descriptor in core
The low-level driver can read the report descriptor, but it cannot determine driver-specific changes to it. The hid core can fixup and parse the report descriptor during driver attach, but does not have direct access to the descriptor when doing so. To be able to handle attach/detach of hid drivers properly, a semantic change to hid_parse_report() is needed. This function has been used in two ways, both as descriptor reader in the ll drivers and as a parsor in the probe of the drivers. This patch splits the usage by introducing hid_open_report(), and modifies the hid_parse() macro to call hid_open_report() instead. The only usage of hid_parse_report() is then to read and store the device descriptor. As a consequence, we can handle the report fixups automatically inside the hid core.
