the MTD ERASE interface has inconsistent return values.
Some implementations return the number of erased sectors,
while others return OK (0). It is currently recommended
to uniformly treat ERASE success as OK. Therefore, the
logic for judging the return value of MTD_ERASE in the
FTL erase interface should be changed to check if it is
greater than 0.

Since there is a storage device like RRAM that doesn't
require erasing, the MTD erase function may not exist.
Here, we should first check whether the erase interface
exists before performing the erasing operation.

Accessing RRAM/MRAM from the FTL interface can
cause errors because RRAM lacks an erase interface.
To make RRAM/MRAM compatible with FTL, the FTL layer
erase interface needs to be modified.

When there's no erase function for mtd, we decide if we
need erase_buffer based on this:
1. If we've got bad block marking, we still need the erase buffer.
If a write fails, it's used to read back the entire bad block's
contents before writing to a new block.
2. If we don't have bad block marking, the erase buffer isn't
needed and can be skipped.

This commit removes the dependency of the fakesensor API on
`SENSORS_GNSS`. All of the logic for handling fake GNSS sensors is
conditionally compiled only if GNSS features are enabled. Other fake
sensors can be used without GNSS logic being included in the build.

Calling `virtio_free_buf` or `kmm_free` inside IRQ may lead to dead lock
inside `mm_free`, so we use a free list to store the buffer and reuse it
next time. Fortunately, NuttX only uses one async buffer at same time,
so we don't need to consider how to free the buffer because we won't
have too many in the free list.

The rpmsg_ioctl() function will first obtain the read lock before
traversing g_rpmsg, then the rpmsg_dev_destory function will try
to obtain the write lock.
At this time, rpmsg_ioctl does not release the read lock, resulting
in a deadlock.
To solve this problem, add a standardalone list for the rptun instance
to avoid hold the rpmsg lock when execute rptun_poweroff()

The reference count (upper->crefs) is incremented in timer_open()
only after ensuring it will not overflow, timer_close() is only
called after a successful open. Therefore, crefs should never be
zero when timer_close() is called. The check for crefs > 0 before
decrementing is unnecessary and has been removed to simplify the code.
