clk: rockchip: rk3399: Fix check patch warnings and checks

Browse source 
- CHECK: spaces preferred around that '*'
- CHECK: spaces preferred around that '/'
- CHECK: space preferred before that '|'
- WARNING: macros should not use a trailing semicolon
- CHECK: Unnecessary parentheses around 'fbdiv <= min_fbdiv'
- CHECK: Unnecessary parentheses around 'parent->id == SCLK_MAC'
- CHECK: Unnecessary parentheses around 'parent->dev == clk->dev'
- WARNING: line over 80 characters
- CHECK: Prefer kernel type 'u8' over 'uint8_t'
- Add proper macro definitions arrangements

Note: there are still line over 80 characters and other warnings but
fixing those making code look unreadable, so I kept it as it is.
