Pengpeng Hou 9dcd9f9365 lib: sbi: use unsigned masks for HPM counter 31 ...

The HPM feature detector and CSR emulator build mhpm_mask bits with a
plain signed 1. Both macro families expand through counter 31, so the
last expansion evaluates 1 << 31 and shifts a signed int into its sign
bit.

Use BIT() at both sites. The mask is unsigned and bit 31 is part of the
represented HPM counter set.
