Subject: [PATCH] phy: ti-pipe3: Use TRM recommended settings for SATA DPLL
The AM572x TRM [1], shows recommended settings for the
SATA DPLL in Table 26-8. DPLL CLKDCOLDO Recommended Settings.
Use those settings in the driver. The TRM does not show
a value for 20MHz SYS_CLK so we use something close to the
26MHz setting.
