964f5a91f7 bootloader, esp32: add workaround for Tensilica erratum 572
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.

da179e0098 xtensa: make XTHAL_GET_INTERRUPT, XTHAL_GET_CCOUNT volatile
INTERRUPT and CCOUNT registers will change outside of program control.
Making the inline assembly used to read these registers volatile
indicates this fact to the compiler.

Fixes https://github.com/espressif/esp-idf/issues/2127
