i2c: ocores: Use read_poll_timeout_atomic to avoid false poll timeouts

Browse source

Replace the manual polling loop in ocores_wait() with the kernel helper
read_poll_timeout_atomic(). This simplifies the code and ensures robust
timeout handling.

In particular, the helper guarantees a condition check after the
delay, even if the delay exceeds the timeout, avoiding spurious
timeout errors under load or preemption.
