ARM: OMAP5: Enable support for AVS0 for OMAP5 production devices

OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.

Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.

scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.

On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1
4a0021c4: 03a003e9 ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1
4a0021c8: 03400485 ..@.

MM OPP_NOM:
=> md.l 0x04A0021A4 1
4a0021a4: 038003d4 ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1
4a0021a8: 03600403 ..`.

CORE OPP_NOM:
=> md.l 0x04A0021D8 1
4a0021d8: 000003cf ....
(0x3cf = 975mV) vs nom voltage of 1.040v

Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).

But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.

Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

Data based on OMAP5432 Technical reference Manual SWPU282AF (May
2012-Revised Aug 2016)

NOTE: All collaterals on OMAP5432 silicon itself seems to have been
removed from ti.com, though EVM details are still available:

ARM: OMAP4+: Add support for dynamically selecting OPPs

It can be expected that different paper spins of a SoC can have
different definitions for OPP and can have their own constraints
on the boot up OPP for each voltage rail. In order to have this
flexibility, add support for dynamically selecting the OPP voltage
based on the board to handle any such exceptions.
