[PATCH] platform/x86: panasonic-laptop: add pr_fmt

[Alex Yeo]

Kernel messages originating from panasonic-laptop on dmesg do not
specify its origin.

ex:
[  +6.009811] Unknown hotkey event: 0x0030
[  +0.229942] Unknown hotkey event: 0x0031

Add pr_fmt so that messages from this module now show up as:

[  +0.209860] panasonic_laptop: Unknown hotkey event: 0x0031
[  +0.160149] panasonic_laptop: Unknown hotkey event: 0x0030
