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

From: "J.D. Schroeder" <jay.schroeder@...min.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 the more
accurate frequency of ~34.6 kHz. Actual measured frequencies of the
clock vary from board to board anywhere from 34.4 kHz up to 34.8 kHz.
