Add SDMMC, QSPI and DMA reset defines. These are needed by SPL
so that we can boot from SD card and QSPI.

Add socfpga_per_reset_all() function to reset all peripherals
but the L4 watchdog. This is needed in the SPL.

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.

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.

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.
