[PATCH] imx: Revert "imx: mx6ull: fix REFTOP_VBGADJ setting" and fix comments

[Ye Li]

The change in commit c1af358 (imx: mx6ull: fix REFTOP_VBGADJ setting)
is not correct. According to latest i.MX6ULL fuse table,
the REFTOP_TRIM[2:0] fuse is defined as below. So the previous codes
are correct, only need to fix the comments.

Set the REFTOP_VBGADJ field in PMU_MISC0 register based on the
REFTOP_TRIM fuse:
'000" - set REFTOP_VBGADJ[2:0] to 3'b000
'001" - set REFTOP_VBGADJ[2:0] to 3'b001
'010" - set REFTOP_VBGADJ[2:0] to 3'b010
'011" - set REFTOP_VBGADJ[2:0] to 3'b011
'100" - set REFTOP_VBGADJ[2:0] to 3'b100
'101" - set REFTOP_VBGADJ[2:0] to 3'b101
'110" - set REFTOP_VBGADJ[2:0] to 3'b110
'111" - set REFTOP_VBGADJ[2:0] to 3'b111
