[RFT][PATCH 2/2] regulator: lm363x: Fix n_voltages setting for lm36274

[Axel Lin <axel.lin@ingics.com>]

According to the datasheet http://www.ti.com/lit/ds/symlink/lm36274.pdf:
Table 23. VPOS Bias Register Field Descriptions VPOS[5:0]:
VPOS voltage (50-mV steps): VPOS = 4 V + (Code × 50 mV), 6.5 V max
000000 = 4 V
000001 = 4.05 V
:
011110 = 5.5 V (Default)
:
110010 = 6.5 V
110011 to 111111 map to 6.5 V

So the LM36274_LDO_VSEL_MAX should be 0b110010 (0x32).
The valid selectors are 0 ... LM36274_LDO_VSEL_MAX, n_voltages should be
LM36274_LDO_VSEL_MAX + 1. Similarly, the n_voltages should be
LM36274_BOOST_VSEL_MAX + 1 for LM36274_BOOST.
