platform/x86: ibm_rtl: fix EBDA signature search pointer arithmetic
The ibm_rtl_init() function searches for the signature but has a pointer
arithmetic error. The loop counter suggests searching at 4-byte intervals
but the implementation only advances by 1 byte per iteration.
Fix by properly advancing the pointer by sizeof(unsigned int) bytes
each iteration.
