[PATCH 6/6] arm64: dts: allwinner: a133: Use the A133 CPU OPP table

[Rajan Yadav via B4 Relay]

From: Rajan Yadav <rajanyadav0307@xxxxxxxxx>

Switch the three A133 boards in mainline (Baijie Helperboard A133,
Liontron H-A133L and Teclast P80) from the A100 OPP table to the A133
one, so the speed grade is selected as the vendor does it.

What changes depends on the chip:
- revision A-E parts with a normal marking ID get a0-a2 from the bin
  field, as they get speed0-2 today, with the same voltages; only
  1080 MHz becomes 1008 MHz. The exception is a part whose ICPU and
  PCPU values are in the range for which the BSP forces a0.
- revision F and later parts with a normal marking ID get the a3-a6
  voltages: higher at 408 and 600 MHz, equal or lower from 1008 MHz,
  and 1008 instead of 1080 MHz.
- "high speed" parts get the b grades, with 1416 and 1512 MHz instead
  of 1464 MHz.
- if the firmware does not provide SMCCC SOC_ID, the driver keeps the
  A100 selection, adds the BSP's a0 rule for normal parts and warns at
  boot.

All three boards supply the CPUs from AXP803 DCDC2 with a 0.81-1.2 V
range, which covers every new voltage. Without the A133 support in
sun50i-cpufreq-nvmem the A100 fallback applies. The Teclast P80 also
needs "cpufreq: sun50i: Handle boards with the allwinner,sun50i-a133
compatible" to get cpufreq at all.

Claude Code (Anthropic) drafted this change and its message; I
reviewed it. I tested the A133 table on a KickPi K5C; I cannot test
these three boards.
