brcm47xx: bgmac: allow bigger et_swtype nvram variable
Without this patch it is impossible to read et_swtype, because the 1 byte space is needed for the terminating null byte. Now it should be possible to read decimal and hex vars of max 8 bit. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 37999
