[PATCH v2 1/2] jiffies: Define secs_to_jiffies()

[Easwar Hariharan <eahariha@linux.microsoft.com>]

secs_to_jiffies() is defined in hci_event.c and cannot be reused by
other call sites. Hoist it into the core code to allow conversion of the
~1150 usages of msecs_to_jiffies() that either:
- use a multiplier value of 1000 or equivalently MSEC_PER_SEC, or
- have timeouts that are denominated in seconds (i.e. end in 000)

This will also allow conversion of yet more sites that use (sec * HZ)
directly, and improve their readability.
