[PATCH 5/5] arm: socfpga: agilex5: drop bank select before ddr_init

[Michael Tretter <m.tretter@pengutronix.de>]

I verified that the bank select on UART0 is not necessary for the
ddr_initialization. Thus, the documentation why the bank select is
necessary is not valid anymore.

Furthermore, depending on the UART used by the board, using UART0 may
not be general enough, anyway.

It seems like the bank select rather added a delay before the SDRAM
initialization and without the bank select, the serial didn't show
anything because the SDRAM initialization failed.

Remove the workaround.
