After all these years intel_bios_reader and intel_bios_dumper still
manage to confuse me. Read or dump, which one decodes. Rename
intel_bios_reader to intel_vbt_decode to be in line with the naming of
all the other tools (particularly the closely related
intel_opregion_decode tool) that decode previously gathered or dumped
information.

-SYNOPSIS
-========
-
-**intel_bios_reader** [*OPTIONS*]
-
-DESCRIPTION
-===========
-
-**intel_bios_reader** is a tool to parse the Intel Video BIOS Tables (VBT) and
-present the information in a human readable format.
-
-The preferred ways of getting the binary VBT to parse are:
-
-1) /sys/kernel/debug/dri/0/i915_vbt (since kernel version 4.5)
-
-2) /sys/kernel/debug/dri/0/i915_opregion
-
-3) Using the **intel_bios_dumper(1)** tool.
-
-The VBT consists of a VBT header, a BIOS Data Block (BDB) header, and a number
-of BIOS Data Blocks.
-
-OPTIONS
-=======
-
---file=FILE
- Parse Video BIOS Tables from FILE.
-
---devid=DEVID
- Pretend to be PCI ID DEVID. Some details can be parsed more accurately if
- the platform is known.
-
---panel-type=N
- Parse the details for flat panel N. Usually this is retrieved from the
Video
- BIOS Tables, but this can be used to override.
-
---all-panels
- Parse the details for all flat panels present in the Video BIOS Tables.
-
---hexdump
- Hex dump the blocks.
-
---block=N
- Dump only the BIOS Data Block number N.
