rtc: sunplus: fix format string for printing resource 

[ Upstream commit 08279468a2 ]

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.
