[PATCH 6.1 386/451] remoteproc: stm32: use correct format strings on 64-bit

[ 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':
drivers/remoteproc/stm32_rproc.c:122:22: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'size_t' {aka 'long unsigned int'} [-Werror=format=]

122 | dev_dbg(dev, "map memory: %pa+%x\n", &mem->dma, mem->len);

drivers/remoteproc/stm32_rproc.c: In function 'stm32_rproc_get_loaded_rsc_table':
drivers/remoteproc/stm32_rproc.c:646:30: error: format '%zx' expects argument of type 'size_t', but argument 4 has type 'int' [-Werror=format=]
drivers/remoteproc/stm32_rproc.c:646:66: note: format string is defined here
646 | dev_err(dev, "Unable to map memory region: %pa+%zx\n",
| ~~^
| |
| long unsigned int
| %x

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