According to the datasheet, the od shift of sys_pll is actually 16.

The fixed_pll also has a fractional part. On axg s400 board, without
this parameter, the calculated rate is off by ~8Mhz (0,4%). The fixed_pll
being the root of the peripheral clock tree, this error is propagated to
the rest of the clocks
Adding the definition of the parameter fixes the problem

Read-only plls don't need param table to recalculate the rate.
Providing them with a param table is just a waste of memory.
Remove the useless tables from sys_pll on gxbb and axg.

platform_get_resource() may return NULL, add proper
check to avoid potential NULL dereferencing.
This is detected by Coccinelle semantic patch.

Fixes the following sparse warning:

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
