since the judgment for network card selection was changed from IS_UP to
IS_RUNNING, drivers that lack carrier_on need to add the carrier_on
operation; otherwise, network access issues will occur.

Currently, the SCTLR register is only used to switch the thread MTE state and has no other uses. Because saving this register is special, it will take a long time after testing, so the default saving behavior is deleted.

Move the board-specific phy initialization from early boot into ifup phase. The
board specific phy initialization may need to implement delays, or bus
communication, for example via i2c bus.
These OS services are not necessarily available yet in arm64_netinitialize, and
PHY initialization is not necessary until the driver actually starts using it.
In addition, this allows the board to reset the ethernet phy at every ifup,
if needed for error recover.

The return address stored in the frame should point to the instruction
after the call. To get the actual call site, we need to subtract the
instruction size (sizeof(void *)) from the saved return address.
This ensures that backtrace addresses correctly point to the calling
instruction rather than the next instruction.

when we build with greenhills compiler, if the exception_common function
is put into a separate section: ".text.exception_common", then the
address of exception_common function is an even number, for example "0x16a6c",
in this case, it will trigger the UsageFaults:INVSTATE error.
The reason for this error is that in the GHS compiler, a section declared
through the ".section" directive must specify at least the "a" attribute.
Otherwise, this section will not be linked into the final file, and this
is why the address of exception_common function is invalid.
The following is the official explanation in the GHS compiler documentation:
"The reason for this error is that in the GHS compiler, a section
declared through the .section directive must specify at least the "a"
