Add support for Sipeed's Lichee Pi 4A board which based on T-HEAD's
TH1520 SoC, only minimal device tree and serial console are enabled,

This RISC-V ACLINT specification [1] defines a set of memory mapped
devices which provide inter-processor interrupts (IPI) and timer
functionalities for each HART on a multi-HART RISC-V platform.
The RISC-V ACLINT specification is defined to be backward compatible
with the SiFive CLINT specification, however the device tree binding
is a new one. This change updates the sifive clint ipi driver to
support ACLINT mswi device, by checking the per-driver data field of
the ACLINT mtimer driver to determine whether a syscon based approach
needs to be taken to get the base address of the ACLINT mswi device.

StarFive VisionFive 2 has two versions, 1.2A and 1.3B, each version of
DDR capacity includes 2G/4G/8G, a DT can not support multiple
capacities, so the capacity size information is recorded to EEPROM, when
DDR initialization required capacity size information is read from
EEPROM.
If there is no information in EEPROM, it is initialized with the default
size defined in DT.

- operating points - these operating points should not be set at the

- clock output names - there are defines for the clock indices, these
should not be needed
- the dt maintainers in linux NAKed using defines for IRQ numbers

In current linker script both .efi_runtime_rel and .rela.dyn sections
are of RELA type whose entry size is either 12 (RV32) or 24 (RV64).
These two are arranged as a continuous region on purpose so that the
prelink-riscv executable can fix up the PIE addresses in one loop.
However there is an 'ALIGN(8)' between these 2 sections which might
cause a gap to be inserted between these 2 sections to satisfy the
alignment requirement on RV32. This would break the assumption of
the prelink process and generate an unbootable image.

So far we used inline assembly to inject the actual instruction that
triggers the semihosting service. While this sounds elegant, as it's
really only about a few instructions, it has some serious downsides:
- We need some barriers in place to force the compiler to issue writes
to a data structure before issuing the trap instruction.
- We need to convince the compiler to actually fill the structures that
we use pointers to.
- We need a memory clobber to avoid the compiler caching the data in
those structures, when semihosting writes data back.
- We need register arguments to make sure the function ID and the
pointer land in the right registers.
This is all doable, but fragile and somewhat cumbersome. Since we now
have a separate function in an extra file anyway, we can do away with
all the magic and just write that in an actual assembler.
This is much more readable and robust.
