Adds addresses and names for individual CSR registers to device tree.
This way liteuart driver no longer depends on CSR data width being 8
bits.
Also when register names or their number changes, then overlay generated
by LiteX will be incompatible with one defined here.
This should make finding breaking changes easier.
I also appended `_ADDR` suffix to defines, to distinguish them from
normal values like `LITEETH_EV_RX`.

This way timer driver no longer depends on CSR data width being 8 bits.
Also when register names their number changes, then overlay generated by
LiteX will be incompatible with one defined here.
This should make finding breaking changes easier.
I also updated register names to those used in current LiteX and
appended `_ADDR` suffix to defines which lacked them.
Because register `total` was renamed to `value` and `update_total` to
`update_value` I updated variables accordingly as well.

Changes signature so it takes uint32_t instead of pointer to a
register.
Later `sys_read*` and `sys_write*` functions are used, which cast
given address to volatile pointer anyway.
This required changing types of some fields in LiteX GPIO driver and
removal of two casts in clock control driver.
There was a weird assert from LiteX GPIO driver, which checked whether
size of first register in dts was a multiple of 4.
It didn't make much sense, so I removed it.
Previous dts was describing size of a register in terms of subregisters
used. New one uses size of register, so right now it is almost always
4 bytes.
Most drivers don't read register size from dts anyway, so only changes
had to be made in GPIO and clock control drivers.
Both use `litex_read` and `litex_write` to operate on `n`bytes.
Now GPIO driver calculates this `n` value in compile time from given
number of pins and stores it in `reg_size` field of config struct like
before.
Registe sizes in clock control driver are hardcoded, because they are
tied to LiteX wrapper anyway.
This makes it possible to have code, independent of CSR data width.
