Add RK3399 eFuse write (OTP programming) support, gated on the presence
of an optional VQPS programming supply in the device tree.
Changes in v2:
- Replaced the rockchip,efuse-write-enable boolean property (v1) with
a proper optional vqps-supply regulator, as suggested by Heiko
Stuebner. The supply presence acts as the hardware-level gate for
write support; the driver owns regulator sequencing entirely inside
the write callback (enable before A_PGM strobe loop, disable after).
- Removed stale debug dev_info() left from development.
- Fixed checkpatch: removed blank line after while open-brace in
rockchip_rk3399_efuse_read().
