arch/risc-v: register Wi-Fi IRQs in non_iram mask for SPI flash

Browse Source 
Wi-Fi used a locally allocated vector_desc, so those CPU interrupt lines
were never recorded in the HAL non_iram_int_mask.
During SPI flash, esp_intr_noniram_disable() therefore did not mask them,
and Wi-Fi ISRs could still run with the cache off.
Now, Wi-Fi IRQs are treated as non-IRAM and get masked while flash/cache is suspended.
