nvmem: meson-efuse: indicate that this driver is only for Meson GX SoCs

Browse Source 
The current Amlogic Meson eFuse driver only supports the 64-bit SoCs
(GXBB and newer). Older SoCs cannot be supported by the same driver
because they do not use the meson secure monitor firmware to access the
hardware.
