so if hpd status on hardware is disconnected, not to read edid.

If we use the channels which are less than en_always_grps_num,
we don't need to set the flag to skip_grps which are not used.
And, the skip grps need to refer to mapped_grps
For example, if:
rockchip,en-always-grps = <1 2 3>;
rockchip,adc-grps-route = <2 1 3 0>;
The DUT startup and capture 2ch at first, we just open grp2
and set skip_grp[2]=1.
Then, if we capture 4ch, we just skip grp2, open grp1, and
set skip_grp[1]=1.
To capture 6ch: we skip grp2/grp1, open grp3 and set skip_grp[3]=1.
To capture 8ch: we skip grp2/grp1/grp3 and open grp0.

The Seagate Expansion Portable Drive HDD (idVendor=0bc2, idProduct=2321)
is reported to fail to work on rockchip platforms with the following error
message when do read/write operation by dd command:
xhci-hcd xhci-hcd.11.auto: Ring expansion failed
According to tkaiser's suggestion[1], we can try to increase the kernel's
coherent-pool memory size to fix this issue. The kernel coherent-pool memory
size was limited at 256KB by default. When set the DEFAULT_DMA_COHERENT_POOL_SIZE
to 1MB, the error "Ring expansion failed" can be fixed, but it still not
work with the other error message:
xhci-hcd xhci-hcd.12.auto: ERROR Unknown event condition 34 for slot 1 ep 3 , HC probably busted
sd 0:0:0:0: [sda] tag#16 uas_eh_abort_handler 0 uas-tag 17 inflight: CMD OUT
...
scsi host0: uas_eh_bus_reset_handler start
xhci-hcd xhci-hcd.12.auto: ERROR Transfer event for disabled endpoint slot 1 ep 6 or incorrect stream ring
Falling back to USB mass storage can solve this problem, so ignore UAS
function of this HDD.

When playing NLPCM audio, such as AC3, HDMI is pluged in, it's
better to reset audio fifo and sync audio clock by reselect
