spl: dm: Kconfig: split REGMAP/SYSCON support for TPL from SPL 

This change introduces TPL variants of the REGMAP and SYSCON config
options (i.e. TPL_REGMAP and TPL_SYSCON in analogy to SPL_REGMAP and
SPL_SYSCON) in preparation of a finer-grained feature selection for
building feature-rich TPL variants.

help
Hardware peripherals tend to have one or more sets of registers
which can be accessed to control the hardware. A register map
models this with a simple read/write interface. It can in principle
support any bus type (I2C, SPI) but so far this only supports
direct memory access.

Many SoCs have a number of system controllers which are dealt with
as a group by a single driver. Some common functionality is provided

assigning a unique number to each.
