Pull request overview
This PR adds Device Manager (DM) support to the RT-Thread serial driver subsystem. The changes introduce multiple new serial drivers compatible with the DM framework while updating existing serial utilities.
Key changes:
- Replaces atomic function from
rt_hw_atomic_addtort_atomic_addin serial_dm.c - Fixes TTY device check to return NULL instead of asserting for non-UART devices
- Adds new serial drivers: 8250 family (OFW, PCI, DWC, early), virtual serial (graphic+input), HVC early serial, and ARM PL011

|---|---|
| components/drivers/serial/serial_tty.c | Changed assertion to graceful NULL return for non-UART devices |
| components/drivers/serial/serial_dm.c | Replaced rt_hw_atomic_add with rt_atomic_add, improved comment style |
| components/drivers/serial/device/virtual/* | New virtual serial driver using framebuffer and input devices |
| components/drivers/serial/device/serial-pl011.c | New ARM PL011 UART driver with DM support |
| components/drivers/serial/device/serial-early-hvc.c | New HVC hypervisor console early driver |

Critical Issues Found:
- 🔴 Incorrect register read/write syntax in 8250-pci.c (lines 55, 65)
- 🔴 Wrong inb() function call syntax in core.c (line 242)
- 🔴 Potential API incompatibility with rt_atomic_add replacement
Just return if is not a tty device, don't assert Signed-off-by: GuEe-GUI <2991707448@qq.com>
