ARM: dts: microchip: sama7g5: Fix RTT clock

[ Upstream commit 867bf1923200e6ad82bad0289f43bf20b4ac7ff9 ]

According to datasheet, Chapter 34. Clock Generator, section 34.2,
Embedded characteristics, source clock for RTT is the TD_SLCK, registered
with ID 1 by the slow clock controller driver. Fix RTT clock.
