Subject: [PATCH] ARM: sunplus: use %pap to print resource_size_t

Prevent a printk format warning by using %pap, which is designed for
this purpose and can handle any size of resource_size_t.

../drivers/rtc/rtc-sunplus.c: In function 'sp_rtc_probe':
../drivers/rtc/rtc-sunplus.c:243:33: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Wformat=]
  243 |         dev_dbg(&plat_dev->dev, "res = 0x%x, reg_base = 0x%lx\n",

Fixes: 0aa94eea8d95 ("ARM: sunplus: Add initial support for Sunplus SP7021 SoC")
