esp8266/modules/flashbdev: Remove code to patch bootloader flash size.
This code is no longer pertinent for some time - since switchover to SDK2.0, there must be correct flash size set for bootloader, or there's a risk of flash data corruption. And indeed, the correct flash size is by default auto-detected by esptool.py 1.2.
