8a30e3a73a arm: socfpga: reset: FIX address of tstscratch register
The Cyclone V Hard Processor System Technical Reference Manual in the
chapter about the Reset Manager Module Address Map stats that the offset
of the tstscratch register ist 0x54 not 0x24.

c624d07f3f arm: socfpga: reset: correct dma, qspi, and sdmmc reset bit defines
The DMA, QSPI, and SD/MMC reset bits are located in the permodrst register,
not the mpumodrst. So the bank for these reset bits should be 1, not 0.

a71df7aa4f arm: socfpga: reset: Replace ad-hoc reset functions
Replace all those ad-hoc reset functions, which were all copies
of the same invocation of clrbits_le32() anyway, with one single
unified function, socfpga_per_reset(), with necessary parameters.

bdfc2ef64a arm: socfpga: reset: Implement unified function to toggle reset
Implement function socfpga_per_reset(), which allows asserting or
de-asserting reset of each reset manager peripheral in a unified
manner. Use this function throughout reset manager.

1115cd2de7 arm: socfpga: reset: Start reworking the SoCFPGA reset manager
Implement macro SOCFPGA_RESET(name), which produces an abstract
reset number. Implement macros which allow extracting the reset
offset in permodrstN register and which permodrstN register the
reset is located in from this abstract reset number. Use these
macros throughout the reset manager.
