Revert "ARM: dts: bcm283x: increase dwc2's RX FIFO size"
This reverts commit 278407a53c3b33fb820332c4d39eb39316c3879a.
The original change breaks USB config on Raspberry Pi Zero and Pi 4 B,
because it exceeds the total fifo size of 4080. A naive attempt to reduce
g-tx-fifo-size doesn't help on Raspberry Pi Zero. So better go back.
