Subject: [PATCH AUTOSEL 5.1 01/95] ARM: dts: dra76x: Disable rtc target module

From: Keerthy <j-keerthy@...com>

[ Upstream commit f7b9cb944a5d41fdede4e928a47e9d5fce5169d7 ]

rtc is fused out on dra76 and accessing target module
register is causing a boot crash hence disable it.

Fixes: 549fce068a3112 ("ARM: dts: dra7: Add l4 interconnect hierarchy and ti-sysc data")
