ectool: Remove CROS_EC_DEV_IOCRDMEM
On !LPC EC, we can read memory via CROS_EC_DEV_IOCXCMD ioctl, using command EC_CMD_READ_MEMMAP. On platform that supports direct memory access (lpc), we access the memory directly, bypassing the ioctl. BUG=chromium:602832 TEST=On gnawty and veyron, check 'ectool battery' works. Verify that gnawty use io mapped registers.
