Fix mutex locking bugs and improve performance. Fix interval no longer
set statically since it is available via `set_interval` uORB function.
Activation/deactivation no longer triggers standby/hotstart since this
functionality was very unstable.

Changes the implementation of the L86xxx driver to use the
gnss_lowerhalf driver implementation, simplifying this driver's logic.
It also fixes the `read_line` function which would early return on `\r`,
as well as adding some retries for response checking and better mutex
locking.

Sometimes this driver will boot when the serial port is of the wrong
baud rate, and it cannot set the correct baud rate or verify
communication. This commit prevents registration if any settings fail to
be set, and also prevents the kernel thread from setting the L86 to
enabled (this is done only by the uORB upper half).

This commit removes the termios dependency of the command to set fix
rate. It makes the MINMEA dependency present in the Kconfig options for
the driver, and it also adds a retry limit to the boot message
verification of 3 times. The documentation has been updated to reflect
the correct signature for the registration function and fix some
formatting.
