[kernel][riscv64] Avoid generating .got in start.S code This cleans up the start.S code to be a little tighter in its reuse of computations in registers. For the one place this code relies on loading a relocated value, it now uses an explicit RELRO data word instead of letting the assembler / linker generate an implicit .got entry with the same relocation. This makes it easier to rule out .got in the ELF kernel image, since all other instances would be undesired compiler-generated cases or other accidental uses in assembly (e.g. `la` used vs `lla`).
