Subject: [PATCH] x86/timers: Move simple_udelay_calibration past
init_hypervisor_platform
This ensures that adjustments to x86_platform done by the hypervisor
setup is already respected by this simple calibration.
The current user of this, introduced by 1b5aeebf3a92 ("x86/earlyprintk:
Add support for earlyprintk via USB3 debug port"), comes much later
into play.
Fixes: dd759d93f4dd ("x86/timers: Add simple udelay calibration")
