Borislav Petkov e35c93695c i2c: ismt: Fix undefined behavior due to shift overflowing the constant 
Fix:

  drivers/i2c/busses/i2c-ismt.c: In function ‘ismt_hw_init’:
  drivers/i2c/busses/i2c-ismt.c:770:2: error: case label does not reduce to an integer constant
    case ISMT_SPGT_SPD_400K:
    ^~~~
  drivers/i2c/busses/i2c-ismt.c:773:2: error: case label does not reduce to an integer constant
    case ISMT_SPGT_SPD_1M:
    ^~~~

See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
details as to why it triggers with older gccs only.
