Boyan Karatotev c9f352c362 fix(cpus): clear CPUPWRCTLR_EL1.CORE_PWRDN_EN_BIT on reset 
The model has a bug where it will not clear CPUPWRCTLR_EL1 on reset,
even though the actual cores do. The write of 1 to the bit itself
triggers the powerdown sequnece, regardless of the value before the
write. As such, the bug does not impact functionality but it does throw
off software reading it.

Clear the bit on Travis and Gelas as they are the only ones to require
reading it back.
