Subject: [RESEND PATCH 01/37] nvmem: sunxi_sid: Drop the workaround on A64

From: Samuel Holland <samuel@...lland.org>

Now that the SRAM readout code is fixed by using 32-bit accesses, it
always returns the same values as register readout, so the A64 variant
no longer needs the workaround. This makes the D1 variant structure
redundant, so remove it.
