Add Doxygen pages for RT-Thread device-model drivers: platform/OFW,
DM core (bus, dm, power), clk/regulator/reset/power-domain, PCI/PIC,
Phye, DMA/hwcache, block/SCSI/ATA/NVMe/UFS/SDIO, SCMI, RPMsg,
mailbox, NVMem, NUMA, syscon, thermal, input/LED/IIO/graphic, and
related power/charger/supply docs.
Expand device-driver INDEX.md with ~90 @subpage entries so all new
pages appear in the driver chapter navigation.
Update existing UART/SPI/RTC/pin/framework/dtc pages: UART docs moved
from serial/ to uart/ (uart + uart_dm + uart_earlycon); SPI and RTC
gain DM companion pages; pin links to pin_dm; framework points at DM
topics.
Focus on registration/probe flow and in-tree APIs; no standalone
VirtIO subsystem page (transport code still incomplete).
Test plan: build Doxygen for documentation/ and verify device-driver
INDEX links resolve without missing @ref/@subpage warnings.

When msh tries to execute a non-ELF path, lwp_execve() may allocate a PID
before lwp_load() fails. The old error path only dropped the LWP reference,
leaving the PID tree entry pointing to a freed LWP.
In an init-less boot flow, this can poison pid 1 after a failed command from
msh. A later LWP launch may then treat the stale pid 1 entry as a valid parent
LWP, resulting in invalid pgrp/session state and a job-control assertion during
process exit.
Add lwp_pid_rollback() for exec/spawn failures before the process becomes
runnable. Unlike lwp_pid_put(), it always releases the PID lock and does not
enter the "no more pid allocation" state when the PID tree becomes empty.
Use the rollback helper in lwp_execve() failure paths after PID allocation.

serial device
- The serial_fops_open function closes and reopens the serial device,but the RT_DEVICE_FLAG_STREAM flag was not preserved across the close/open cycle. This change saves the STREAM flag before close and restores it during reopen to ensure consistent behavior.

When rx_bufsz or tx_bufsz is 0, the driver returns -RT_EPERM but falls
through to RT_ASSERT(rx_fifo/tx_fifo != RT_NULL). Since serial_rx/serial_tx
is NULL in non-buffered mode, this triggers an assertion failure.
Add break after setting ret = -RT_EPERM in the four affected cases:
- RT_SERIAL_CTRL_SET_RX_TIMEOUT
- RT_SERIAL_CTRL_SET_TX_TIMEOUT
- RT_SERIAL_CTRL_GET_RX_TIMEOUT
- RT_SERIAL_CTRL_GET_TX_TIMEOUT
