esp32/boards: Compile GENERIC_SPIRAM and UM_TINYPICO with -Os.

stephanelsmith · dpgeorge · commit ae3d5289a5fa · 2022-04-14T16:06:41.000+10:00
These boards do not build with IDF v4.4 because the section .iram0.text does not fit in region iram0_0_seg. Enabling SPIRAM increases the code size so use -Os instead of -O2 to build these boards. Fixes issue micropython#8260.
