Nuttx currently has 2 types of sleep interfaces:
1. Signal-scheduled sleep: nxsig_sleep() / nxsig_usleep() / nxsig_nanosleep()
Weaknesses:
a. Signal-dependent: The signal-scheduled sleep method is bound to the signal framework, while some driver sleep operations do not depend on signals.
b. Timespec conversion: Signal-scheduled sleep involves timespec conversion, which has a significant impact on performance.
2. Busy sleep: up_mdelay() / up_udelay()
Weaknesses:
a. Does not actively trigger scheduling, occupy the CPU loading.
3. New interfaces: Scheduled sleep: nxsched_sleep() / nxsched_usleep() / nxsched_msleep() / nxsched_ticksleep()
Strengths:
a. Does not depend on the signal framework.
b. Tick-based, without additional computational overhead.
Currently, the Nuttx driver framework extensively uses nxsig_* interfaces. However, the driver does not need to rely on signals or timespec conversion.
Therefore, a new set of APIs is added to reduce dependencies on other modules.
(This PR also aims to make signals optional, further reducing the code size of Nuttx.)

Currently the mdio communication is part of the monolithic 'full netdevs'.
This commit serves as an way to add modularity for the netdevs drivers.
A new upperhalf/lowerhalf mdio device comes with this commit that manages the data transfer ofer mdio interface.

Add driver for the Onsemi NCV7410 10BASE-T1S SPI MAC-PHY.
The driver also works for the NCN26010, which is an identical chip.
The driver is a lower-half driver to the OA-TC6 base driver.

Instead of verifying MMD indirect access by checking
EEE ADVERTISEMENT register has value 0x6 (which may be changed),
the verification is done by write and check LED MODE register.
1. Backup current LED_MODE register value
2. Write value Single-LED mode (0x10) to LED_MODE
3. Read LED_MODE register and verify it returns value 0x10
4. Write original (backup) value to LED_MODE
From the ksz9477 errata, setup the configuration which is tested to work.
- Improve PHY receive performance
- Disable EEE for ports 1-5
- Fix supply current values

This commit removes existing support for the NCV7410 10BASE-T1S MAC-PHY.
The driver will be replaced by its generalized version with different organization.
The new driver has naming clashes with the old, therefore the old has to be removed first.

A descriptor ring length must be aligned to 128, one descriptor is 16B length,
so we can provide this condition with the appropriate number of descriptors

Descriptor head is managed by HW and should not be modified by SW unless:
1. device is after a reset
2. device is before enabling TX or RX
Also set correct tail for RX which should point at the end of ring
(descriptor ring is zero-indexed).

Do not reset RX/TX rings when link status change.

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.

Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.
