4f762cb409 perf vendor events riscv: Update SiFive Bullet events
Regenerate the event lists from the original hardware description. This
makes them consistent with the event lists for newer versions of the
hardware, allowing most files to be reused across hardware versions.

0d042fa514 perf vendor events riscv: Remove leading zeroes
The EventCode field (as stored in the mhpmeventN CSRs) is actually 56
bits wide, but there is no need to keep leading zeroes in the JSON
files. Remove them to simplify review of the following change, which
regenerates the files in a way that does not include leading zeroes.

This change was performed automatically with `sed -i "s/0x0*/0x/"`.

d35ad7e881 perf vendor events riscv: Rename U74 to Bullet
This set of PMU event descriptions applies not only to the SiFive U74
core configuration, but also to other SiFive cores that implement the
Bullet microarchitecture (such as U64, P270, and X280). Rename the
directory to be more generic.
