[PATCH v2] checkpatch: mention fsleep() in MSLEEP and USLEEP_RANGE warnings

[Neel Bullywon]

Expand the MSLEEP warning to also reference fsleep() alongside
msleep(), and expand the USLEEP_RANGE check to reference fsleep()
alongside usleep_range() and udelay(). fsleep() autoselects the
best sleep mechanism based on duration, making it a useful
alternative for developers to consider.

Changes in v2:
- Keep existing warning text and expand to mention fsleep() instead
  of replacing the msleep() reference (Andy).
- Also update the USLEEP_RANGE check to mention fsleep() (Andy).
