x86/boot/Documentation: Fix htmldocs build warning due to malformed table in boot.rst

Sphinx reports htmldocs warnings:

  Documentation/arch/x86/boot.rst:437: ERROR: Malformed table.
  Text in column margin in table line 2.

The table header defined the first column width as 2 characters ("=="),
which is too narrow for entries like "0x10" and "0x13". This caused the
text to spill into the margin, triggering a docutils parsing failure.

Fix it by extending the first column of assigned boot loader ID to 4
characters ("====") to fit the widest entries.
