[PATCH v2] platform/x86: yogabook: Clean up code style

[Benjamin Philip]

This commit cleans up the following checks flagged by checkpatch in
yogabook.c:

- CHECK: Prefer kernel type 'u8' over 'uint8_t'
- CHECK: Comparison to NULL could be written "!data"
- CHECK: line length of ... exceeds 100 columns

Signed-off-by: Benjamin Philip <benjamin.philip495@gmail.com>
---
Changes in v2:
  - Drop cleanup for "CHECK: Unnecessary parentheses around '...'"

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
