Subject[PATCH 0/2] nvmem: meson-efuse: add write support
This changeset adds write support to meson efuse driver.
The first patch just changes the way the nvmem data are allocated w/o
any functional changes. The second patches actually adds write support.

The memory being an OTP, it is safer if it remains read-only by default,
which is why I also submitted this DT patch [0].

If a user knows what he is doing, it should be easy to remove the
read-only property from the board DT. This can be done in u-boot, before
starting linux:

> fdt rm /efuse read-only

Tested on the gxl libretech-cc
