lsi53c895a: Implement write access to DMA Byte Counter
Adds CASE_SET_REG24 and fixes the following errors: lsi_scsi: error: Unhandled writeb 0x24 = 0x0 lsi_scsi: error: Unhandled writeb 0x25 = 0x0 Signed-off-by: Sebastian Herbszt <herbszt@gmx.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
