lib: Use __ASSEMBLER__ instead of __ASSEMBLY__

Convert all non-x86 #ifdefs from __ASSEMBLY__ to __ASSEMBLER__, and remove
all manual __ASSEMBLY__ #defines. __ASSEMBLY_ was inherited blindly from
the Linux kernel, and must be manually defined, e.g. through build rules
or with the aforementioned explicit #defines in assembly code.

__ASSEMBLER__ on the other hand is automatically defined by the compiler
when preprocessing assembly, i.e. doesn't require manually #defines for
the code to function correctly.

Ignore x86, as x86 doesn't actually rely on __ASSEMBLY__ at the moment,
and is undergoing a parallel cleanup.

riscv: Add DT parsing

Start building setup() by copying code from Arm and adding
dependencies along the way like bitops and a few more barriers.
We now parse the DT for the UART base address to be sure we
find what we expect with the early base. We also parse the
CPU nodes to get the hartids, even though we don't yet support
booting secondaries. Finally, add parsing of bootargs to get
the command line and parsing of the environ to set the environment
variables, and then extend the selftest to ensure it all works.

We don't do proper memory setup yet, only just enough to allocate
memory for the environment variables and any another small mallocs
that may be necessary.

Note, we've added a banner, which Arm doesn't have, because we
need to separate the test output from OpenSBI output.

Run with
qemu-system-riscv64 -nographic -M virt \
-kernel riscv/selftest.flat \
-append 'foo bar baz' \
-initrd test-env \
-smp 16

where test-env is a text file with the environment, i.e.
$ cat test-env
FOO=foo
BAR=bar
BAZ=baz

lib/linux/const.h: test for `__ASSEMBLER__` as well

On s390x we're using the preprocessor for generating our linker scripts
out of assembly files. The macro `__ASSEMBLER__` is defined with value 1
when preprocessing assembly language using gcc. [1] Therefore, let's
check for the macro `__ASSEMBLER__` in `lib/linux/const.h` as well. Thus
we can use macros that makes use of the `_AC` or `_AT` macro in the
"linker scripts".

lib: add linux dir for kernel uapi headers

We needed to import some uapi headers, e.g. lib/arm/asm/uapi-psci.h,
and will need some others, e.g. pci_regs.h, in the future. Create a
linux directory for them in lib so that they can be included with
the familiar <linux/header.h> reference.

(Note, x86 has been cheating. lib/x86/pci.c already includes
<linux/pci_regs.h>, which it's been getting away with as its include
paths are less strict than arm's, i.e. it *does* look in /usr/include)
