Referring to platform_get_irq()'s definition, the return value has
already been checked if ret < 0, and printed via dev_err_probe().
Calling dev_err_probe() one more time outside platform_get_irq()
is obviously redundant.
Removing dev_err_probe() outside platform_get_irq() to clean up
above problem.

Convert platform_get_resource_byname(),devm_ioremap_resource() to a single
call to devm_platform_ioremap_resource_byname(), as this is exactly what
this function does.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

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.

If devm_ioremap_resource() fails, it should return error
code from sp_rtc->reg_base in sp_rtc_probe().
