esp8266/modules/flashbdev: Remove code to patch bootloader flash size.

Paul Sokolovsky · Paul Sokolovsky · commit 4a72294d7d49 · 2017-01-05T22:26:23.000+03:00
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.
