MSPM0C1104: SPI Recieve Problem

What did you transmit to get the RX data? SPI can only receive as part of a transmit. Your device may have a dummy NOP byte that is used for the peripheral to send data.

>  SPI_RX_data  = DL_SPI_receiveData8(SPI_0_INST); 

I suspect you aren't waiting for the exchange (Tx/Rx) to complete. Try instead something like:

>  SPI_RX_data  = DL_SPI_receiveDataBlocking8((SPI_0_INST); 

I'm just guessing at the context here, but it will probably look something like:

DL_SPI_transmitDataBlocking8(SPI_0_INST, register_read); // Request
DL_SPI_transmitDataBlocking8(SPI_0_INST, 0xFF); // Dummy byte to receive value
(void)DL_SPI_receiveDataBlocking8(SPI_0_INST); // Read and throw away Request Rx
SPI_RX_data  = DL_SPI_receiveDataBlocking8(SPI_0_INST); // Capture register value

As per the above i was not impleminting    (void)DL_SPI_receiveDataBlocking8(SPI_0_INST); // Read and throw away Request Rx

in my code, Now i am able to read the Data from SPI , BUt now after to read sequence the data is getting shifted .

I have observe that when I write the SPI periphrial once and then i tried to read the SPI Peripherial first time it is not read properly and then it when continuos read then it read properly . Anything to be writeen in the code after the Write data is completed.

Is the data shifted bit-wise or byte-wise? 

For bit-wise:

1) Make sure your SCK polarity and phase (CPOL/CPHA) match the RTC's. This would be in the RTC datasheet.

2) Long wires can introduce propagation delay. I've seen bit-shift/bit-smear with 12cm wires at 6MHz. Try slowing your SPI down.

For byte-wise:

1) With the SPI, every Tx byte generates an Rx byte (as seen above). You need to account for each one to maintain the correspondence.

it is shifted Byte wise.   should i have to read the Receive buffer by using  SPI_RX_data  = DL_SPI_receiveDataBlocking8(SPI_0_INST);  and dump the data ???

after every Tx byte

Usually, yes.
