Subject: [PATCH] HID: appletb-kbd: Use secs_to_jiffies() instead of msecs_to_jiffies()

Use secs_to_jiffies() instead of msecs_to_jiffies() and avoid scaling
the module params 'appletb_tb_idle_timeout' and 'appletb_tb_dim_timeout'
to milliseconds. secs_to_jiffies() expands to simpler code and reduces
the size of 'hid-appletb-kbd.ko'.

Reformat the code to silence multiple checkpatch warnings.

No functional changes intended.
