morris 73031f7280 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 5e21717fed 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 c513f95ebb 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).

morris 0469db2f83 refactor(rcc): unify the usage of clock control macros for peripherals 
- Removed conditional definitions for various RCC_ATOMIC macros across
multiple files, replacing them with a unified PERIPH_RCC_ATOMIC() macro.
- Updated instances where specific RCC_ATOMIC macros were used to ensure
consistent usage of PERIPH_RCC_ATOMIC().
- Deleted unused uart_share_hw_ctrl.h file as its functionality is now
integrated into the new structure.
