api: Remove deprecated Notepads

Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.

In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:

16 32-bit integers were allocated.
A total of 64 bytes per task per thread.

This is especially critical in low memory and safety-critical applications.

They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.

Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.

1	Description: Motorola MCF5329EVB Zoom + (LogicPD)
2	============
3	CPU: MCF5329, 240MHz
4	CORESRAM: 32K
5	FLASH: 2M
6	DRAM: 32M
7
8	This is a Motorola Zoom evaluation board that uses the MCF5329 Coldfire CPU on
9	a logicPD card. This board is running at 240MHz with DRAM clocking at 80MHz.
10
11	The bsp is configured for the MT46V16M16TG-75:F DRAM.
12
13	NOTES:
14	======
15
16	This BSP is based heavily off the 5235 BSP.
17
18	TODO:
19	======
20
21	Add other drivers for can, i2c, lcd (fb), qspi etc.
