Initial release of Flash bank driver for Bouffalo chips. The driver currently supports BL602, BL702, BL702L series of chips. Similar SFlash core is inside of BL808, BL606P and BL616 series, so those might be supported in future as well. With adapter speed set to 8000, it can reach speed 140 KiB/s. Since chips have eXecute In Place support, and they also require boot config in Flash at offset 0x0, it's required to have properly crafted linker script, so OpenOCD knows where to write firmware through gdb. There is required flash bank parameter, which specifies the chip type. This is required because BL702 and BL702L have same TAP ID CODE, and there are no usable indicators to use for automatic chip type recognition in the chip.
