esp32: Move FAT FS to start at 0x200000 and increase size to 2MiB.

MrSurly · dpgeorge · commit f6547f640378 · 2017-04-13T10:29:10.000+10:00
This allows for more room (up to 2MiB) for the firmware, and also gives a
decent size filesystem.

After using this patch one is required to rebuild their filesystem.
