controller would send repend hci data until host send back h5 ack.

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();

The recv buffer is used both in user thread and rpmsg ept->callback
thread, so add recv lock to protect the recv buffer.

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.

Make sure that interrups are disabled during initialization.
This is a proper fix for an unexpected MSI interrupt for PCI 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.

add support for UART 16550 compatible PCI device.
For now we support qemu serial PCI devices and AX99100 based cards.

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

move MCR_OUT2 configuration from qemu-intel64/src/qemu_boot.c to common code
also leave this option disabled for qemu-intel64 as it's not required

If failed in pty_register2, it is possible to enter unregister_driver
function, which eventually calls ptmx_minor_free, resulting in mutex
conflict.
