flash: stm32f1x: Pad odd byte writes early to avoid 16-bit writes
For odd byte counts, stm32x_write() pads the last byte and writes it using a discrete 16-bit access. The stlink debugger can't issue 16-bit writes so it fails for odd byte writes. This patch changes stm32x_write() to pad odd byte writes into a new buffer and use the normal code path with a single block write. The fallback path, when working area cannot be allocated, has to use 16-bit writes though which means that sufficient working area is required for stlink and odd byte writes.
