[PATCH 5.10 207/238] remoteproc: stm32: use correct format strings on 64-bit

[Sasha Levin]

From: Arnd Bergmann <arnd@xxxxxxxx>

[ Upstream commit 03bd158e1535e68bcd2b1e095b0ebcad7c84bd20 ]

With CONFIG_ARCH_STM32 making it into arch/arm64, a couple of format
strings no longer work, since they rely on size_t being compatible
with %x, or they print an 'int' using %z:

drivers/remoteproc/stm32_rproc.c: In function 'stm32_rproc_mem_alloc':

Fix up all three instances to work across architectures, and enable
compile testing for this driver to ensure it builds everywhere.
