[PATCH 02/11] riscv: update asm call site in `call_on_irq_stack` to setup correct label

[Deepak Gupta <debug@rivosinc.com>]

Call sites written in asm performing indirect call, they need to setup
label register (t2/x7) with correct label.

Currently first kernel was compiled with `-save-temps` option and
normalized function signature string is captured and then placed at the
asm callsite.

TODO: to write a macro wrapper with toolchain support.
