Add some """"low-hanging"""" SD driver error code bits
* 3rd line is: <code>print_string(..., "%08X %08X", *((unsigned int*)(0x1FFFE000+0x10))`, `*((unsigned int*)(0x1fffe000+0x14)));//See below memory notes.</code>

* 4th line is: <code>print_string(..., "%08X %08X",*((unsigned int*)(0x1FFFE000+0x18))`, `*((unsigned int*)(0x1fffe000+0x1C)));//See below memory notes.</code>

=== BootROM SD device error bits ===
These error codes are received directly from the device, and are in the same format as received in an R1 type reply.
See [https://www.sdcard.org/downloads/pls/ SD Specifications Part 1 Physical Layer Simplified Specification] for the error bit list.
