staging: greybus: fix stack size warning with UBSAN

clang warns about excessive stack usage in this driver when
UBSAN is enabled:

drivers/staging/greybus/audio_topology.c:977:12: error: stack frame size of 1836 bytes in function 'gbaudio_tplg_create_widget' [-Werror,-Wframe-larger-than=]

Rework this code to no longer use compound literals for
initializing the structure in each case, but instead keep
the common bits in a preallocated constant array and copy
them as needed.

staging: r8188eu: use a delayed worker for led updates

The led layer uses a combination of timer and worker for periodic led
updates, e.g. for blinking. The reason seems to be that blocking
operations like a usb read are not allowed in a timer handler.

Replace the combination of timer and worker with a delayed worker.

Convert the timeout defines from milliseconds to jiffies to make them
usable as delays for the delayed worker. Shorten the names of the defines
and rename the work item to make checkpatch happy.

Other layers may call SwLedControlMode1 to update the led state. Such
an update may result in cancelling the delayed worker. SwLedControlMode1
might be called in interrupt context, we must use cancel_delayed_work to
cancel the worker. cancel_delayed_work_sync waits until the worker is
finished, this is not allowed in interrupt context.

DeInitLed871x is called when the driver is removed or when the system
goes into standby. We may use cancel_delayed_work_sync here to cancel
the delayed worker.

staging: fbtft: add macro FBTFT_REGISTER_SPI_DRIVER

After 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT
compatible") we need to add spi id_tables. Changing existing macro
FBTFT_REGISTER_DRIVER would have meant to change arguments and
therefore adjust all fbtft drivers.

This patch adds a new and simplified macro FBTFT_REGISTER_SPI_DRIVER
that includes a spi id_table, and in addition to that:
- does not define a platform driver
- uses macro module_spi_driver()
