riscv: Fix builtin DTB handling
All SiPeed K210 MAIX boards have the exact same vendor, arch and implementation IDs, preventing differentiation to select the correct device tree to use through the SOC_BUILTIN_DTB_DECLARE() macro. This result in this macro to be useless and mandates changing the code of the sysctl driver to change the builtin device tree suitable for the target board.
Fix this problem by removing the SOC_BUILTIN_DTB_DECLARE() macro since it is used only for the K210 support. The code searching the builtin DTBs using the vendor, arch an implementation IDs is also removed. Support for builtin DTB falls back to the simpler and more traditional handling of builtin DTB using the CONFIG_BUILTIN_DTB option, similarly to other architectures.

treewide: Convert macro and uses of __section(foo) to __section("foo")
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.
Conversion done using the script at:

riscv: Allow device trees to be built into the kernel
Some systems don't provide a useful device tree to the kernel on boot. Chasing around bootloaders for these systems is a headache, so instead le't's just keep a device tree table in the kernel, keyed by the SOC's unique identifier, that contains the relevant DTB.
This is only implemented for M mode right now. While we could implement this via the SBI calls that allow access to these identifiers, we don't have any systems that need this right now.

riscv: Add SOC early init support
Add a mechanism for early SoC initialization for platforms that need additional hardware initialization not possible through the regular device tree and drivers mechanism. With this, a SoC specific initialization function can be called very early, before DTB parsing is done by parse_dtb() in Linux RISC-V kernel setup code.
This can be very useful for early hardware initialization for No-MMU kernels booted directly in M-mode because it is quite likely that no other booting stage exist prior to the No-MMU kernel.
Example use of a SoC early initialization is as follows:
static void vendor_abc_early_init(const void *fdt) { /* * some early init code here that can use simple matches * against the flat device tree file. */ } SOC_EARLY_INIT_DECLARE("vendor,abc", abc_early_init);
This early initialization function is executed only if the flat device tree for the board has a 'compatible = "vendor,abc"' entry;
