rtc: sunplus: fix format string for printing resource
On 32-bit architectures with 64-bit resource_size_t, sp_rtc_probe() causes a compiler warning: drivers/rtc/rtc-sunplus.c: In function 'sp_rtc_probe': drivers/rtc/rtc-sunplus.c:243:33: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Werror=format=] 243 | dev_dbg(&plat_dev->dev, "res = 0x%x, reg_base = 0x%lx\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The best way to print a resource is the special %pR format string, and similarly to print a pointer we can use %p and avoid the cast.
