[PATCH] riscv: ptrace: avoid BIT() in UAPI header

[Michael Neuling]

BIT() is not available in UAPI headers — the installed linux/bits.h
(UAPI version) does not define it. Replace BIT() with open-coded
(1UL << x) which is the standard practice for UAPI headers, and drop
the linux/bits.h include that was added by commit 98545620b0 ("riscv:
ptrace: Fix BIT() compilation issues").

Fixes: 98545620b0 ("riscv: ptrace: Fix BIT() compilation issues")
