lcd: Fix incorrect use of LCD_STRIDEFORMAT for remote LCDs
The get_address_fn implementations for some remote LCDs were checking LCD_STRIDEFORMAT unconditionally, but that macro is only valid for the main LCD. The remote LCD code only supports horizontal strides, so when compiling for a remote LCD, force the use of horizontal stride addressing. This fixes a buffer overflow and out of bounds write that occurs with the M:Robe 500 remote LCD. (Tested with sim + ASan only.) Change-Id: I99c6aa11d38f5105b096fc448948b9ec1b27dfe6
