[PATCH 3/4] riscv: ptrace: Fix BIT() compilation issues

[Charlie Jenkins via B4 Relay]

From: Charlie Jenkins <thecharlesjenkins@xxxxxxxxx>

BIT() is being used in ptrace.h without a definition, resulting in
compilation errors in tools/testing/selftests/riscv/cfi/cfitests.c:

cfitests.c:101:60: error: implicit declaration of function ‘BIT’ [-Wimplicit-function-declaration]
  101 |                      if ((cfi_reg.cfi_status.cfi_state & CFI_ENABLE_MASK) != CFI_ENABLE_MASK)

Include linux/bits.h to resolve this issue.

Fixes: 2af7c9cf021c ("riscv/ptrace: expose riscv CFI status and state via ptrace and in core files")
