Make directory hierarchy flat to match the same layout we use

for other chipsets, as suggested on IRC.

+// Set P6IF DRDY Timing
+// Because there are 1.5T & 2.5T CAS latency in DDR1 mode, we need to use RDELAYMD-0

+//        VIA_NB2HOST_REG54[7:5]        Host Frequency

+// P6IF DRDY Timing Control:
+// *Following algorithm to set DRDY timing
+// Set P6IF DRDY Timing by the following 3      conditions:
+// 1. RDELAYMD
+//    a.RDRPH(MD        input internal timing control)
+//    b.CAS Latency
+//    RDELAYMD(1bit) = bit0 of (CL + RDRPH)
+//    for example: RDRPH=10b, CL3 -> F3_Rx56[5:4]=11b, 10b + 11b        = 101b, RDELAYMD=1 (bit0)
+//                RDRPH=00b, CL2.5 -> F3_Rx56[5:4]=10b, 00b + 10b = 010b, RDELAYMD=0 (bit0)
+// 2. CPU Frequency
+// 3. DRAM Frequency
+//
+// According to above conditions, we create different tables:
+// 1. RDELAYMD=0        : for integer CAS latency(ex. CL=3)
+// 2. RDELAYMD=1        : for non-integer CAS latency(ex. CL=2.5)
+// 3. Normal performance
+// 4. Top performance :
+//                     Using phase0 to a case has better performance.
+//
+// Note: The setting are        related to performance and maybe affect DRAM initialize.
+//      Turn OFF(F2_Rx51[7]=0) this feature at csDRAMRegInitValueJ procedure.
+//      Turn ON(F2_Rx51[7]=1) this feature at csDRAMRegFinalValueJ procedure.
+//
+// If F2_Rx51[7]=0, then        CPU always wait 8QW, a slower but most stable way
+// If F2_Rx51[7]=1, then        the timing will refer to F2_Rx60 ~ F2_Rx67,
+// a fast way but may cause the system to be unstable.
+//
+// Coding:
+// 1. RDELAYMD and user's option        for performance can determine which table
+// 2. CPU Frequency can get block offset        of table
+// 3. DRAM Frequency can        get row offset of block
+// 4. Set value
+//
+// PS: Fun2 Rx62, Rx65, Rx67 are        don't care bits in 3296, CPU 266MHz doesn't be supported by 3296,
+//     but I still keep these bits in table to avoid the        usage in future
+//     and do the fewest        modification for code.
