soc: Allow components to reserve fixed memory ranges that they need
...
No longer necessary to keep all reserved addresses in 'soc'.
Means 'soc' does not need to know about 'bt', for example.
Also means that Bluetooth can be enabled in config without any memory being reserved for BT
controller. Only if code calling the BT controller is linked in, will this memory be reserved...

Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet.
