Official Release: PineTime MCUBoot Bootloader with fixes for SPI hanging, manual firmware rollback

MCUBoot Bootloader that fixes SPI Bus corruption...

1. In case of Non-Maskable Interrupt (e.g. assertion failure) and Hard Fault, blink 4 times quickly and reboot.

2. Assertion failure may be due to SPI Bus corruption, which causes SPI Flash access to fail in spiflash_identify() in repos/apache-mynewt-core/hw/drivers/flash/spiflash/src/spiflash.c. Rebooting fixes the SPI Bus corruption.

   See #24

3. Why blink before rebooting? So that we introduce a delay before rebooting, to prevent reboot looping. If PineTime flashes continuously for a long time, it means that the bootloader is stuck in a reboot loop, possibly due to faulty hardware.

4. Also fixes the checking for manual firmware rollback. Now we need to press and hold at least 1 second, to prevent accidental rollback. During rollback, the screen blinks slowly 4 times before rebooting.

5. Increased Bootloader Flash Area from 24 KB to 28 KB to allow testing of MCUBoot with Semihosting Console enabled. Decreased Reboot Log Flash Area from 8 KB to 4 KB so other Flash Areas are not affected. Updated the Flash Map docs:

From now on, all MCUBoot binaries released have Semihosting Disabled and will work with JLink.
