[PULL 23/24] mac_via: fix rtc command decoding from PRAM addresses 0x0 to 0xf

[Laurent Vivier]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

A comparison between the rtc command table included in the comment and the code
itself shows that the decoding for PRAM addresses 0x0 to 0xf is being done on
the raw command, and not the shifted version held in value.
