MLK-13140 ARM: imx: update REFTOP_VBGADJ according to fuse setting
On i.MX6ULL, according to the latest REFTOP_TRIM fuse define, we need
to set the REFTOP_VBGADJ bits in PMU_MISC0 register as below table:
'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
