Subject: [PATCH] soc: qcom: geni-se: Correct QUP Core ICC vote constants

The GENI_TO_CORE ("qup-core") ICC vote selects the QUP Core 2X clock
rate. The CORE_2X_*_MHZ constants are expressed in Bps, but their
values are several orders of magnitude too small. For example, the
50 MHz threshold is represented by 2500 rather than 25000000 Bps.

As a result, clients using these constants can severely under-vote the
QUP Core clock.

Correct the constants to their intended Bps thresholds so that the ICC
provider selects the corresponding QUP Core 2X clock rate. Drop the unused
definitions.
