This defconfig is an example of the recorded stack and it became
faulty recently after the implementation of the `up_current_regs`
functions. The `noinstrument_function` directive must be used for
preventing it from being looped when instrumentation is enabled.
Also, this commit places `sched/instrument/stack_record.c` in IRAM.
Since the size of the shadow area will change during the script merging of global variables, it will lead to unpredictable number of links. After fixing, only three links are required.

This interface may be used by application specific logic to start
specified slave cpu core under the pseudo AMP case which is different
with armv7-a/armv8-a SMP. Support for this function is required by
board-level logic if CONFIG_BOARDCTL_START_CPU is selected.

Revert "Parallelize depend file generation"
This reverts commit d5b6ec450f.
parallel depend ddc does not significantly speed up compilation,
intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly

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

Some of PCI drivers require OS interfaces that can't be executed in the INIT context.
In that case we have to postpone PCI drivers probing and call it for example
in board initialization logic.

reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

Provides two implementations:
- CSR_CYCLE: Cores which implement hardware performance monitoring.
- CSR_TIME: Uses the machine time registers.
Using the up_perf_xx bindings directory is more efficient than performing a nanosecond conversion on every gettime event.
Basic amg88xx sensor handling (open, close, read, ioctl).
No interrupts supported. I intend to add support for this feature when I
gain more know-how on nuttx/posix.
reason:
BOARDIOC_SPINLOCK can support the combined semantics
of disabling interrupts (irq), trylock, and spinlock.
