Currently the stm32f1x flash driver uses an asynchronous algorithm
as part of the block flash programming. This greatly speeds up flash
programming as the target is always running.
Moving the async code to the target enable other targets to use this
added functionality.

I used the CPUID instead of adding a new argument to the flash bank command
Fixed Type in comments
Add the failsafe return value in device_id

Correct the offset to the read pointer when clearing it on error.
Also restrict the instruction set to armv6-m so the flash driver can be
used on Cortex-M0 parts with the same flash controller.

The stm32 drivers have been using 0x7ff as the DEV_ID mask, this should
have been 0xfff.

Don't call a variable num_pages if it holds the flash size. Also rearrange
flash size to num_pages calculation to avoid divide-by-zero if there will
be a device with < 1024 byte pages someday.

Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

Access the different flash banks' registers using a bank specific register
base and a register specific offset. This is equivalent but feels more
natural.
Some accesses were discovered that maybe should not be hard coded to bank0
registers. Add a note about that.

Use consistent names for the stm32 family flash drivers, eg.
stm32x -> stm32f1x
stm32f2xxx -> stm32f2x
this makes it easier to add support for newer stm32 families.
