The av7110_reset_arm() function in av7110_hw.c is wrapped in an
"#if 0 / #endif" block and therefore not compiled into the driver.
The function name is not referenced from anywhere else in the
av7110 driver tree:

  $ git grep -n av7110_reset_arm drivers/staging/media/av7110/
  (no results after this change)

The actual ARM boot path is implemented by av7110_bootarm(), so the
disabled av7110_reset_arm() is leftover code with no remaining
purpose. Drop it; "#if 0" blocks are dead code and should be
removed rather than kept around (see coding-style.rst, section 21,
"Conditional Compilation").

The "/* av7110 ARM core boot stuff */" section comment is kept,
since it still applies to the helpers that follow (waitdebi(),
load_dram(), av7110_bootarm()).

No functional change.
