b43legacy: avoid PPC fault during resume
commit 316a4d966cae3c2dec83ebb1ee1a3515f97b30ff upstream.
For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43legacy_status()
returns a value of 2 (B43legacy_STAT_STARTED); however, one finds that
the driver is unable to associate after resuming from hibernation unless
this routine returns 1. To satisfy both conditions, the routine is rewritten
to return TRUE whenever b43legacy_status() returns a value < 2.
This patch fixes the second problem listed in the postings for Red Hat
Bugzilla #538523.
