Hello,

This is a belated follow-up from a few of my earlier attempts to fix up the
ARM generic timer for correct behaviour on the ASPEED AST2600 SoC. The AST2600
clocks the generic timer at the rate of HPLL, which is configured to 1125MHz.
This is significantly quicker than the currently hard-coded generic timer rate
of 62.5MHz and so we see "sticky" behaviour in the guest.

Please review.
