morris 37758ef327 fix(driver): allocate driver objects containing atomic variables from internal SRAM 
Objects with atomic members must not be allocated to PSRAM, otherwise
the ordering guarantee of atomic accesses is weakened due to a hardware
behavior on ESP32 chips. Explicitly request MALLOC_CAP_INTERNAL |
MALLOC_CAP_8BIT for:

- i2c master bus object (atomic status/trans_idx)
- ISP processor and AE/AF/AWB/HIST controllers (atomic fsm)
- JPEG decoder/encoder dma2d transaction descriptors (atomic started)
- PPA transaction storage embedding dma2d_trans_t
- dma2d m2m test transaction embedding dma2d_trans_t

morris 80aa3978b3 fix(i2c): release platform mutex on intr/pm_lock delete failure 
ESP_RETURN_ON_ERROR inside the s_i2c_platform.mutex critical section
returns without releasing the mutex, permanently blocking all I2C
bus operations. Replace with ESP_GOTO_ON_ERROR that jumps to a
cleanup label releasing the mutex before return.

DatanoiseTV ae669c7049 fix(i2c_master): yield from ISR when no matching device is found 
`i2c_master_isr_handler_default()` may set HPTaskAwoken to pdTRUE via
`xQueueSendFromISR()` (event_queue), `xSemaphoreTakeFromISR()` and
`xSemaphoreGiveFromISR()` on `bus_lock_mux`. When the device list lookup
returns no matching device, the function returned directly, skipping
the `portYIELD_FROM_ISR()` at the bottom of the handler. A higher-
priority task waiting on the bus mux or the event queue would then have
to wait for the next scheduler tick instead of being preempted into
immediately, inflating worst-case event latency.

Replace the early return with a goto to the existing yield check at the
end of the ISR.

Chen Chen 230b7b5892 fix(i2c): reset master before bus clear on chips without HW FSM reset 
Reorder s_i2c_hw_fsm_reset() so i2c_ll_reset_register and interrupt
masking run before s_i2c_master_clear_bus(). Avoids ISR firing when
i2c_common_set_pins reconnects GPIOs to a stuck FSM (IDFGH-17497).
