sgxfreq: set correct frequency limit on omap4460/4470
Commit 5e398ba changes how the initial frequency limit is selected: instead of selecting the highest avaliable one, it hardcodes it to SYS_SGX_CLOCK_SPEED, which is defined as 307200000 Hz for SGX540_120. However, omap4460/4470 devices use 384000000 Hz, so we end up underclocking them. Instead of hardcoding these frequencies, let's just use them as a reference frequency, and use the first frequency that is less than or equal to the correct reference frequency. This way, we can ensure a safe frequency set on kernels with custom SGX clock frequencies enabled. Change-Id: Ic55be55dbb5c9d4a3807096209cdf07bbbdca719
