acpuclock-7627.c: fixing table selection in select_freq_plan()

In the function 'select_freq_plan()' there's a check to select
the correct table for 1008Mhz CPU's, because there's a conflict
between 7627AA and 8625 chips.

However this check is wrong:
	if (pll_mhz[ACPU_PLL_2] == 245)

It should be:
	if (pll_mhz[ACPU_PLL_1] == 245)

We don't want to check PLL_2 but PLL_1 being '245' or not.

Due of this bug the wrong frequency table is getting selected
for 1GHz 8625 chips with PLL_2=245.

drivers/cpufreq: conservative: simplify SAMPLING_TIME determination for ARM

...because simple things can be good things, too.

This commit introduces MIN_SAMPLING_RATE & DEF_SAMPLING_RATE
which are used to directly set the driver's minimum and default
sampling rate rather than doing any calculation before.
