Add driver for controlling the reset lines of AN7581. This is a detached
version of the clock controller driver present in Linux only used to
control reset lines. Driver gets loaded with the bind of the clock
driver and doesn't require a compatible. This is needed as they share
the same registers.

Add support for Airoha AN7581 SoC clock driver. This mainly needed for
eMMC support to correctly get the current clock applied.
Based on the Linux clk-en7523.c but majorly reworked for U-Boot that
doesn't require CCF subsystem.
Major modification, support for set_rate, realtime get_rate and split
for reset part to a different driver.

Now that we have everything in place switch the page permissions for
.rodata, .text and .data just after we relocate everything in top of the
RAM.
Unfortunately we can't enable this by default, since we have examples of
U-Boot crashing due to invalid access. This usually happens because code
defines const variables that it later writes. So hide it behind a Kconfig
option until we sort it out.
It's worth noting that EFI runtime services are not covered by this
patch on purpose. Since the OS can call SetVirtualAddressMap which can
relocate runtime services, we need to set them to RX initially but remap
them as RWX right before ExitBootServices.

The ARM ARM (Rev L.a) on section 8.17.1 describes the cases where
break-before-make is required when changing live page tables.
Since we can use a function to tweak block and page permissions,
where BBM is not required split the existing mmu_change_region_attr()
into two functions and create one that doesn't require BBM. Subsequent
patches will use the new function to map the U-Boot binary with proper
page permissions.
While at it add function descriptions in their header files.

Upcoming patches are switching the memory mappings to RW, RO, RX
after the U-Boot binary and its data are relocated. Add
annotations in the linker scripts to and mark text, data, rodata
sections and align them to a page boundary.
It's worth noting that .efi_runtime memory permissions are left
untouched for now. There's two problems with EFI currently.
The first problem is that we bundle data, rodata and text in a single
.efi_runtime section which also must be close to .text for now.
As a result we also dont change the permissions for anything contained
in CPUDIR/start.o. In order to fix that we have to decoule .text_rest,
.text and .efi_runtime and have the runtime services on their own
section with proper memory permission annotations (efi_rodata etc).
The efi runtime regions (.efi_runtime_rel) can be relocated by the OS when
the latter is calling SetVirtualAddressMap. Which means we have to
configure those pages as RX for U-Boot but convert them to RWX just before
ExitBootServices. It also needs extra code in efi_tuntime relocation
code since R_AARCH64_NONE are emitted as well if we page align the
section.
Due to the above ignore EFI for now and fix it later once we have the
rest in place.

Add a new config option under "General setup" to enable the -Werror flag
when building U-Boot. This is useful during development to help catch
mistakes.
This is based on a similar config option added to the Linux kernel by
Linus in 2021 - see Linux commit 3fe617ccafd6 ("Enable '-Werror' by
default for all kernel builds"). The modification of KBUILD_CFLAGS is
done in Makefile.extrawarn, matching where it was moved in the kernel by
Linux commit e88ca24319e4 ("kbuild: consolidate warning flags in

Now that we have the same option for SPL and TPL, simplify the logic for
