Tiago Medicci Serrano 63364a52ff esp32s3/spiflash: pause other CPU before SPI flash operations
Whenever a SPI flash operation is going to take place, it's
necessary to disable both the instruction and data cache. In order
to avoid the other CPU (if SMP is enabled) to retrieve data from
the SPI flash, it needs to be paused until the current SPI flash
operation finishes. All the code that "pauses" the other CPU (in
fact, the CPU spins until `up_cpu_resume` is called) needs to run
from the instruction RAM.
