[ALSA] pcxhr - Fix the crash with REV01 board
On a new board revision for pcxhr boards, the PCXHR_CHIPSC_GPI_USERI bit is no more supported. The cards concerned have a REV01 in their PCI ID. As the current driver tests this bit and does not load the first Xilinx binary when it's 1, the card will crash on Xilinx access over PCI. (the PCI will freeze ....) The fix (fix to version 1.0.11rc4) works for both REV00 and REV01 cards. Signed-off-by: Takashi Iwai <tiwai@suse.de>
