2da8cb6af5 powerpc/mpc5121: move PSC FIFO memory init to platform code
Since PSC could also be used in other modes than UART mode
we move PSC FIFO memory initialization from serial driver to
common platform code. The initialized FIFO memory slices may
not overlap, so the most easy way would be to configure them
all at once at init time for all PSC devices. This is now done
by this patch.

6cff46f4bc powerpc: Remove get_irq_desc()
get_irq_desc() is a powerpc-specific version of irq_to_desc(). That
is reason enough to remove it, but it also doesn't know about sparse
irq_desc support which irq_to_desc() does (when we enable it).

87c441e54d powerpc/5xxx: Add common mpc5xxx_get_bus_frequency() function
So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency,
while MPC52xx used mpc52xx_find_ipb_freq().  Despite the different
clock names (IPS vs. IPB) the code was identical.

Use common code for both processor families.

28794d34ec powerpc/kconfig: Kill PPC_MULTIPLATFORM
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.

This removes it along with the following changes:

 - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
   on 6xx which is what they want anyway.

 - A new symbol, PPC_BOOK3S, is defined that represent compliance with
   the "Server" variant of the architecture. This is set when either 6xx
   or PPC64 is set and open the door for future BOOK3E 64-bit.

 - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
   PPC64 && PPC_BOOK3S

 - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
   used to control the use of prom_init.c

- contents of mpc5121_ads_init_IRQ -> mpc512x_init_IRQ
  - looking for fsl,mpc5121-ipic instead of fsl,ipic
- mpc5121_ads_declare_of_platform_devices -> mpc5121_declare_of_platform_devices
