Use floor ops on SDCC1 APPS clock in order to round down selected clock
frequency and avoid overclocking SD/eMMC cards.
For example, currently HS200 cards were failling tuning as they were
actually being clocked at 384MHz instead of 192MHz.
This caused some boards to disable 1.8V I/O and force the eMMC into the
standard HS mode (50MHz) and that appeared to work despite the eMMC being
overclocked to 96Mhz in that case.
There was a previous commit to use floor ops on SDCC clocks, but it looks
to have only covered SDCC2 clock.

ftrace: Fix assuming build time sort works for s390
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

Add a test which allows us to test parsing an event alias with hyphens.
