Use the proper structure which describes these registers,
especially since this is already in place.

Remove the remaining invocations of sdr_get_addr() and the function
itself. This makes the code a bit less cryptic.

Instead of this indirection, just adjust the register pointer and
directly use the register base address.

It is the configuration data that should go into the register,
not the register mask, just like the surrounding code does it.
Fix this typo.

42f7ebb82b ddr: altera: Move struct sdram_prot_rule prototype
Move the structure prototype from sdram.h header file into sdram.c
source file, since it is used only there and for local purpose only.
There is no point in having it global.

While at this move, fix the data types in the structure from uintNN_t
to uNN and fix the coding style a bit.

9bbd2132e3 driver/ddr/altera: Add DDR driver for Altera's SDRAM controller
This patch enables the SDRAM controller that is used on Altera's SoCFPGA
family. This patch configures the SDRAM controller based on a configuration
file that is generated from the Quartus tool, sdram_config.h.
