This beeper hardware requires a PWM driver for frequency selection.
Since the GPIO driver does not provide that, revert the beeper
support to a simple gpio-export.
This effectively reverts the corresponding changes from

After those symbols have been removed from generic kernel config,
they were added to the target config during every kernel config
refresh. As that's not desirable, add them back to the generic
config.

Not a large change from last time, but should fix at least one rare wave-2
crash. The htt-mgt-community builds are trimmed for supporting lots of
stations (typically 150+ stations per radio).
Tested on Netgear R7800.

In commit 87b35c16ad ("kernel: ubifs: create use file system format 4
by default") we changed the default UBIFS version used when the kernel
creates a new volume from 5 to 4. UBIFS v5 was added in kernel 4.10 and
only kernel 4.10 and later can read it.
We changed the kernel to create version 4 volumes also on more recent
kernel versions to make it possible to downgrade to an OpenWrt version
with kernel 4.9, the upgrade still works. This is probably not needed
any more and we can remove this patch.

The CDROM is not needed for booting and can be included by selecting the
loadable module as a package instead.
This also avoids triggering a memory allocation failure during probing of
the CDROM due to lack of low 16MB DMA memory, as decribed in FS#3278:

After years of trying to find the reason for random kernel crashes
while both CPU and SATA are under load it has been found.
Some odd commented-out #defines in kref's single-port driver [1] which
were copied from the vendor driver made me develop a theory:
The IO-mapped memory area for DMA descriptors apparetly got some holes
just before the alignment boundaries.
This feels like an off-by-one bug in the hardware or maybe those fields
are used internally by the SATA controller's firmware.
Whatever the cause is: they cannot be used and trying to use them
results in reading back unexpected stuff and ends up with oopsing
Unable to handle kernel paging request at virtual address d085c004
Work around the issue by reducing the area used for bmdma descriptors.
This reduces SATA performance (iops) quite a bit, but finally makes
things work reliably. Possibly one could optimize this much more by
really just skipping the holes in that memory area -- however, that
seems to be non-trivial with the driver and libata in it's current form
(suggestions are welcome).
The 'proper' way to have good SATA performance would be to make use of
the hardware RAID features (one can use the JBOD mode to access even
just a single disc transparently through the RAID controller integrated
in the SATA host instead of accessing the SATA ports 'raw' as we do
now).
