net: stmmac: clarify priv->pause and pause module parameter
priv->pause corresponds with "pause_time" in the 802.3 specification,
and is also called "pause_time" in the various MAC backends. For
consistency, use the same name in the core stmmac code.
Clarify the units of the "pause" module parameter which sets up this
struct member to indicate that it's in units of the pause_quanta
defined by 802.3, which is 512 bit times.
