bbb7f436d4 serial.c: should protect the fds when calling poll_notify 
1. Use critical_section to protect the fds array;
2. Use critical_section and sched lock to protect the poll notify, because
   poll notify may cause context switch, delay the context swtich to
   sched_unlock();

4cec713dbf fs_inode:Change the type of i_crefs to atomic_int 
Summary:
  1.Modified the i_crefs from int16_t to atomic_int
  2.Modified the i_crefs add, delete, read, and initialize interfaces to atomic operations
The purpose of this change is to avoid deadlock in cross-core scenarios, where A Core blocks B Core’s request for a write operation to A Core when A Core requests a read operation to B Core.

d4bbbe0d0b drivers/pty: support pty write to send signal, like serial driver 
The interaction between the shell service in adb and adbd occurs through a pseudo-terminal (pty).
so, when a command is launched through adb shell from a PC, users now have the ability to pause
or kill the launched,application by inputting specific commands CONFIG_TTY_SIGTSTP_CHAR or
CONFIG_TTY_SIGTINT_CHAR, akin to the capabilities provided by nsh.

prepare 16550 UART driver to support PCI:

- [breaking change] change argument of uart_ioctl() from `struct file *filep` to `FAR struct u16550_s *priv`
  Also fix moxart_16550.c build related to this change

- [breaking change] change argument of uart_getreg() and uart_putreg from `uart_addrwidth_t base` to `FAR struct u16550_s *priv`
  Also fix arch/x86/src/qemu/qemu_serial.c and arch/x86_64/src/intel64/intel64_serial.c related to this change

- [breaking change] change argument of uart_dmachan() from `uart_addrwidth_t base` to `FAR struct u16550_s *priv`

- move `struct u16550_s` to public header

- generalize UART_XXX_OFFSET so we can use it with any register increment

- make u16550_bind(), u16550_interrupt(), u16550_interrupt() public

- remove arch/or1k/src/common/or1k_uart.c and use common 16550 MIMO interfacve

- change irq type in `struct u16550_s` from uint8_t to int to match MSI API
