 The function  init_programmable_clock() references

 This is often because init_programmable_clock lacks a __init

In this case the only calls to and from init_programmable_clock()

According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"c4d1fb62", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.

We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.
