[PATCH 4/6] arm64: dts: allwinner: a100: Add A133 speed grade efuse cells

[Rajan Yadav via B4 Relay]

From: Rajan Yadav <rajanyadav0307@xxxxxxxxx>

The A133 speed grade selection also needs the chip marking ID (SID
offset 0x00), the word at 0x20, whose low 12 bits the vendor BSP calls
PCPU, and the word at 0x28 with the bin extension bit. Add nvmem cells
for them at the offsets the BSP uses. The H616 reads the same kind of
marking ID at offset 0x00 as its speed grade.

The cells are used by the A133 OPP table added later in this series;
the A100 OPP table keeps using only the existing 0x1c cell.

Claude Code (Anthropic) drafted this change and its message from the
vendor BSP device tree; I reviewed it and checked it with dtbs_check.
