Michal Lenc 425ddc7f72 lcd/st7789: fix incorrect buffer count for 3 wire RAM write 
If st7789_wrram is called with count = 1, then the entire buffer should
be sent. However, in 3 wire mode, the driver has to send the buffer
row by row because of additional data flag. The number of rows (count)
can't be ST7789_YRES in this case, but only the number of rows in
the buffer (this is write size / row size , where row size is
ST7789_XRES * ST7789_BYTESPP). This also applies only if we want to
write size larger than row size, because st7789_putrun allows to
write just a part of a row.

This fixes the incorrect behavior of the display in 3 wire mode if
the display is split into more buffer writes (as in LCD driver for
example, FB driver did not face this issue).
