hpwdt: Only BYTE reads/writes to WD Timer port 0x72
This patch is to correct the use of the iLO port 0x72 usage. The port 0x72 is a byte size write/read and hpwdt is currently writing a WORD. Signed-off by: Thomas Mingarelli <thomas.mingarelli@hp.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
