This adds `make flash` support for the rp2040 target. Flashing is
performed using a custom `rp2040_flash` tool that uses the PICOBOOT
protocol. Root is not required.
The user specifies the serial device of the rp2040 they wish to flash as
the device. This device is reset into bootsel mode and `rp2040_flash`
is invoked on the original USB device path.
If the device is already in bootloader mode, the user can specify
'first' as `FLASH_DEVICE` which will simply invoke `rp2040_flash` with
no bus/address options.

Commit ae89a659 caused a regression in the lpc176x UART handling.
After that commit the UART clock divisor would need to be 6.25 on
lpc1768 or 7.5 on lpc1769, but the code only supports whole numbers.
Set the PCLKSELx registers at startup and return to using full speed
peripheral clocks.

Now that the lpc176x code uses the armcm_boot mechanism, it is no
longer necessary for SystemInit to be externally visible.

Now that the stm32f1 code has been merged into the stm32 code, there
is no longer a need to use the upstream stm32f1 "hal" code.

Update the stm32f1 code to the latest from ST. Merge the
lib/cmsis-stm32f1/ and lib/hal-stm32f1/ into a single lib/stm32f1/
directory. Document all the differences from the pristine upstream
code.

These two files from atmel have different licenses than the other
files. Neither files provide any real value, so just remove them to
avoid any confusion.
