scsi: ufs: move dme peer quirk handling to ufshcd_dme_get_attr()
Some UFS host controllers may only allow accessing the peer DME attribute
in AUTO mode (FAST AUTO or SLOW AUTO) hence we had added a quirk for
switching to AUTO power mode before accessing the peer DME attribute.
But this quirk handling was only done in UFS driver's debugfs handling
hence this patch moves it to main driver ufshcd.c so that this quirk
handling is applied to all the peer DME accesses.
As we are doing this, this patch fixes 2 more related problem:
1. Current quirk was only handling the switch from FAST to FAST AUTO hence
this change adds the handling for SLOW to SLOW AUTO mode change as well.
2. ufsdbg_dme_read() helper function was always reading the local DME
attribute hence this change fix the same.
