[DistroKit] [PATCH] v7a: images: stm32mp: double STM32MP15 fip partition size to 2M

[Ahmad Fatoum]

Our FIP image contains barebox as non-trusted firmware, a hardware
device tree and a very small firmware config as well as the secure
monitor, either from TF-A or OP-TEE.

This clocks in at 617K for STM32MP15, where we don't use OP-TEE and 986K
on STM32MP13, where we do use it.

The STM32MP13 has a separate genimage config, which has a 2M FIP
partition already. Let's follow suit for STM32MP15 to allow for more
convenient experimentation and debugging, e.g. enabling Kernel
AddressSanitizer in barebox already makes it to big to fit inside a 1M
fip partition.

Note: this is already effectively included in my barebox unification series:
<20250526101147.1953428-5-rhi@pengutronix.de> (2025-05-26, Roland Hieber:
"[DistroKit] [PATCH 05/11] v7a: stm32mp: switch to upstream barebox recipe") 
(where the size of the partition is removed in favour of specifying it in the
fit image config).

Nice, this patch can be disregarded then.

Thanks,
