habanalabs/gaudi: Use correct sram size macro for debugfs

Browse Source 
We currently allow accessing the whole SRAM bar size with
the macro SRAM_BAR_SIZE, but the actual size of the sram
region is the macro SRAM_SIZE which is only a portion of
the whole bar size. So when accessing the sram through
debugfs, use the macro SRAM_SIZE for the sram size
which is the correct macro.
