Kristian Evensen d238c7f995 mediatek: Fix memory node for U7623 
The changed applied to BananaPi R2 in upstream commit c0b0d540db1a,
which was backported to 4.14 in 4.14.53, is also required for the U7623.
Without updating the memory node, the board refuses to boot.

Fixes: d0839e020d ("kernel: bump 4.14 to 4.14.53")
