rockchip: spl: do full dram_init instead of only probing

Parts of later SPL may need RAM information as well, so do full
dram_init() call, which includes the existing dram probing but also
initializes the ram information in gd.

dram_init() from sdram.c does the following steps:
- uclass_get_device(UCLASS_RAM, ...) like the current code
- ret = ram_get_info(dev, &ram);
- gd->ram_size = ram.size;

CONFIG_SPL_RAM already makes sure that sdram.c gets compiled
and thus no other variant of dram_init() can exist.

So it's the same functionality as before and only adds that the
SPL now aquires knowledge about the amount of available ram,
which it didn't know about before.
