[PATCH v2 2/3] ARM: DRA7x: dts: Update the OSC_32K_CLK frequency

["J.D. Schroeder" <Linux.HWI@garmin.com>]

From: "J.D. Schroeder" <jay.schroeder@garmin.com>

This commit updates the OSC_32K_CLK (secure_32k_clk_src_ck) frequency
from the precise 32kHz frequency (i.e., 32.768 kHz) to a more
accurate frequency of ~34.6 kHz. Actual measured frequencies of the
clock vary from processor to processor anywhere from 34.4 kHz up to
34.8 kHz. Note that the ~34 kHz frequency clock is generated
internally by the processor, not an input to the processor. This
change makes it more clear that the consumer of the
secure_32k_clk_src_ck will not get a precise 32.768 kHz frequency
output.
