Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

TX clock or ref clock can be driven either from outside (PHY / oscilator) or by the ENET block.
Typical connection with RMII PHY is that the PHY drives the refclk.

Using the HLT instruction in VM usually traps into the Hypervisor and releases CPU control. This will result in real-time performance degradation. Using the NOP or MWAIT instruction for an IDLE loop can reduce energy consumption while not trapping into the Hypervisor.

Change "DMACH_HANDLE *handle" into "DMACH_HANDLE handle". The DMACH_HANDLE is already
defined as "void *".

currently esp32 protected mode requires a patched bootloader.
it's a bit cumbersome to build the bootloader for that purpose.
this commit attempts to remove the need of the patched bootloader
by applying the changes by ourselves using esp hal.
64-by-32-bit divisions are prominent in the NuttX, even on 32-bit
machines. Luckily, many of them use a constant divisor that allows
for a much faster multiplication by the divisor's reciprocal.
The compiler already performs this optimization when compiling a 32-by-32
division with a constant divisor. Unfortunately, on 32-bit machines, gcc
does not optimize 64-by-32 divisions in that case, except for constant
divisors that happen to be a power of 2.
Let's avoid the slow path whenever the divisor is constant by manually
computing the reciprocal ourselves and performing the multiplication
inline. In most cases, this improves performance of 64-by-32 divisions
by about two orders of magnitude compared to the __div64_32() fallback,
especially on architectures lacking a native div instruction.
