v7a: tf-a: update to v2.7

We need at least v2.6 for FIP support, but there's a freshly released
v2.7, so lets use that. This unfortunately means we need to carry a
patch for the MC-1 because upstream broke it.  To ensure the legacy
image works for now, we need to set a new build option, but that will
be removed soon enough with the switch to FIP.

+Subject: [PATCH] fix(stm32mp1): fdts: stm32mp1: align DDR regulators with new
+ driver
+
+With recent changes, TF-A now panics on LXA MC1, Avernger96 and Odyssey:
+
+  NOTICE:  CPU: STM32MP157C?? Rev.B
+  NOTICE:  Model: Linux Automation MC-1 board
+  ERROR:   regul ldo3: max value 750 is invalid
+  PANIC at PC : 0x2ffeebb7
+
+as the driver takes great offense at the content of the device
+tree. The parts in question were copy-pasted from ST DTs, but those
+ST DTs were fixed by commit 67d95409baae
+("refactor(stm32mp1-fdts): update regulator description").
+
+Fix the breakage by transplanting the same changes into all STM32MP1 DTs.
+
+Fixes: bba9fdee589f ("feat(stm32mp1): add regulator framework compilation")
