leds: qpnp-wled: add a secure write API

Currently, for doing a secure write to the peripheral register,
secure access is acquired at the call site before writing to the
register. Optimize this by adding an API to do secure writes.
When a secure write is attempted, it should be atomic and not
raced with normal write. Add a mutex lock to synchronize the
normal and secure writes. While at it, fix the data parameter
passed to qpnp_wled_write_reg() as that doesn't really need a
pointer.
