The GDMA layer used `max_data_burst_size == 0` as the only way to disable the
data burst. That conflicts with the upstream drivers' convention where a zeroed
config struct means "unset", so users had no way to ask for the driver default
burst size.
GDMA now treats both 0 and 1 as "no data burst": a single-beat burst has no
benefit over the non-burst mode. The MSPI alignment constraint under Flash
Encryption / PSRAM ECC still takes precedence and is reported with a warning.
The upstream drivers using GDMA now apply their own default burst size (16
bytes) when the user leaves `dma_burst_size` as 0, following the UHCI driver:
- esp_async_crc (AHB / AXI GDMA backend)
- esp_async_memcpy (AHB / AXI / LP-AHB / DW_GDMA backend)
Callers that really want no burst can now set `dma_burst_size` to 1.
Rename uhci_ll_rx_set_eof_mode → uhci_ll_rx_enable_eof_modes and its
parameter eof_mode → eof_modes to reflect that multiple EOF modes can
be enabled simultaneously via bitmask. Add bool en parameter so callers
can enable or disable without an outer if-check.

The workaround in the commit routes the signal to LP GPIO matrix first.
When uses LP IOMUX pin as UART RX, the signal did not bypass the matrix,
which caused the issue.
This commit adds rtc_gpio_iomux_input and rtc_gpio_iomux_output APIs
to align with existing GPIO driver APIs.
Map logical /dev/console fds to the primary sink fd for select.
This avoids probing UART1/UART2 for stdout/stderr and keeps UART select state consistent.
Add stdio regression checks for logical fd mapping and symmetric uart_end_select teardown.
- Move the linux repl chip and deprecate chip related functions
- Update location of driver specific default config
- Add missing comments on the newly added functions in the affected components.
- 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.
If uart_driver_install is not called before uart_get_baudrate,
the UART port may not be ready. In such cases, the register values
cannot be read out, leading to a division by zero error in uart_ll_get_baudrate.
This commit adds a check to ensure the UART port is enabled before
attempting to read its registers.
