[U-Boot] arm socfpga: Revert "spi: cadence_qspi_apb: Support 32 bit AHB address"

[Frank Mori Hess]

It looks like the change I'm trying to revert got rejected a couple
years ago in another form:

https://lists.denx.de/pipermail/u-boot/2015-August/224556.html

In particular at the end Marek says:

>>  /* Indirect mode configurations */
>>  writel((plat->sram_size/2), plat->regbase + CQSPI_REG_SRAMPARTITION);
>> - writel((u32)plat->ahbbase & CQSPI_INDIRECTTRIGGER_ADDR_MASK,
>> + writel((u32)plat->trigger_base,
>>  plat->regbase + CQSPI_REG_INDIRECTTRIGGER);
