Subject: [PATCH] HID: input: fix mapping for camera access keys

Commit 9f4211bf7f81 ("HID: add mapping for camera access keys") added
mapping for the camera access keys, but unfortunately used wrong usage
codes for them. HUTRR72[1] specifies that camera access controls use 0x76,
0x077 and 0x78 usages in the consumer control page. Previously mapped 0xd5,
0xd6 and 0xd7 usages are actually defined in HUTRR64[2] as game recording
controls.
